I'm using meteor.js and playing around with a simple application. I have a form on my page and once submitted the data is inserted into a database. I have a 'feed' of data on the left side of my page which updates when a new entry in the database is submitted, displaying the data. This is basic data at present about countries and populations etc. My question is how to mix a js variable to vary the source of an image file thats loaded in this 'feed' - hopefully explained below.
So, in code, I have this:
<template name="mainLeftCol">
<div class="col-sm-5">
{{> form}}
</div>
</template>
<template name="mainBody">
{{> mainLeftCol}}
<div class="col-sm-7">
{{#each dbEntry}}
{{> formItem}}
{{/each}}
</div>
</template>
and in a js file I have the event code for when the form is submitted:
Template.mainLeftCol.events({
'submit form': function(e) {
e.preventDefault()
var country = $(e.target).find('[id=country]').val()
prefix = country.slice(0,3);
if (prefix === 'Eng') {
console.log("Eng is for England");
}
var spot = {
country: country,
continent: $(e.target).find('[id=continent]').val(),
};
spot._id = Spots.insert(spot);
}
});
The formItems are being displayed using the following template which outputs the 'variables' that were input in the form:
<template name="formItem">
{{#Animate}}
<div class="panel panel-default spot animate">
<div class="panel-heading">
<h5 class="pull-right">{{country}}</h5>
<h4><mark><b>{{continent}}</b></mark></h4>
</div>
<div class="panel-body">
<img src="Eng.png" class="img-circle pull-right">
</div>
</div>
{{/Animate}}
</template>
As you can see in this template I have hardcoded "Eng.png" as the source for the image. What I would like to do is based on the prefix variable which slices the country field is to have the template display a different image (they're flags) based on the country on the template.
How can I mix a JS variable from my events code into the source of the image file in my template code?
Hope this makes sense!
I don't know if i got i right, but if you want to change the image (flag) according to the country try something like this:
Build a Template helper "prefix" which outputs the current country prefix.
Prefix helper:
Template.formItem.helpers({
countryPrefix: function () {
var country = $(e.target).find('[id=country]').val()
return country.slice(0,3);
}
});
In your Template you can now:
<div class="panel-body">
<img src="{{countryPrefix}}.png" class="img-circle pull-right">
</div>

I have a form inside a modal that I use to edit a review on an item (a perfume). A perfume can have multiple reviews, and the reviews live in an array of nested documents, each one with its own _id.
I'm editing each particular review (in case an user wants to edit their review on the perfume once it's been submitted) by submitting the EditReviewForm to this edit_review route:
#reviews.route("/review", methods=["GET", "POST"])
#login_required
def edit_review():
form = EditReviewForm()
review_id = request.form.get("review_id")
perfume_id = request.form.get("perfume_id")
if form.validate_on_submit():
mongo.db.perfumes.update(
{"_id": ObjectId(perfume_id), <I edit my review here> })
return redirect(url_for("perfumes.perfume", perfume_id=perfume_id))
return redirect(url_for("perfumes.perfume", perfume_id=perfume_id))
And this route redirects to my perfume route, which shows the perfume and all the reviews it contains.
This is the perfume route:
#perfumes.route("/perfume/<perfume_id>", methods=["GET"])
def perfume(perfume_id):
current_perfume = mongo.db.perfumes.find_one({"_id": ObjectId(perfume_id)})
add_review_form = AddReviewForm()
edit_review_form = EditReviewForm()
cur = mongo.db.perfumes.aggregate(etc)
edit_review_form.review.data = current_perfume['reviews'][0]['review_content']
return render_template(
"pages/perfume.html",
title="Perfumes",
cursor=cur,
perfume=current_perfume,
add_review_form=add_review_form,
edit_review_form=edit_review_form
)
My issue
To find a way to get the review _id in that process and have it in my perfume route, so I can pre-populate my EditReviewForm with the current value. Otherwise the form looks empty to the user editing their review.
By hardcoding an index (index [0] in this case):
edit_review_form.review.data = current_perfume['reviews'][0]['review_content']
I am indeed displaying current values, but of course the same value for all reviews, as the reviews are in a loop in the template, and I need to get the value each review_id has.
Is there a way to do this, before I give up with the idea of allowing users to edit their reviews? :D
Please do let me know if my question is clear or if there's more information needed.
Thanks so much in advance!!
UPDATE 2:
Trying to reduce further my current template situation to make it clearer:
The modal with the review is fired from perfume-reviews.html, from this button:
<div class="card-header">
<button type="button" class="btn edit-review" data-perfume_id="{{perfume['_id']}}" data-review_id="{{review['_id']}}" data-toggle="modal" data-target="#editReviewPerfumeModal" id="editFormButton">Edit</button>
</div>
And that opens the modal where my form with the review is (the field in question is a textarea currently displaying a WYSIWYG from CKEditor:
<div class="modal-body">
<form method=POST action="{{ url_for('reviews.edit_review') }}" id="form-edit-review">
<div class="form-group" id="reviewContent">
{{ edit_review_form.review(class="form-control ckeditor", placeholder="Review")}}
</div>
</form>
</div>
Currently this isn't working:
$(document).on("click", "#editFormButton", function (e) {
var reviewText = $(this)
.parents(div.card.container)
.siblings("div#reviewContent")
.children()
.text();
$("input#editReviewContent").val(reviewText);
});
and throws a ReferenceError: div is not defined.
Where am I failing here? (Perhaps in more than one place?)
UPDATE 3:
this is where the button opens the modal, and underneath it's where the review content displays:
<div class="card container">
<div class="row">
<div class="card-header col-9">
<h5>{{review['reviewer'] }} said on {{ review.date_reviewed.strftime('%d-%m-%Y') }}</h5>
</div>
<div class="card-header col-3">
<button type="button" class="btn btn-success btn-sm mt-2 edit-review float-right ml-2" data-perfume_id="{{perfume['_id']}}" data-review_id="{{review['_id']}}" data-toggle="modal" data-target="#editReviewPerfumeModal" id="editFormButton">Edit</button>
</div>
</div>
<div class="p-3 row">
<div class=" col-10" id="reviewContent">
<li>{{ review['review_content'] | safe }}</li>
</div>
</div>
</div>
You can do this with jQuery as when you open the form, the form will automatically show the review content in there. It will be done by manipulating the dom.
Also, add an id to your edit button, in this example, I have given it an id "editFormButton".
Similarly, add an id to the div in which review content lies so that it is easier to select, I have given it an id "reviewContent"
Similarly, add an id to edit_review_form.review like this edit_review_form.review(id='editReviewContent')
<script>
$(document).on("click", "#editFormButton", function (e) {
var reviewText = $(this)
.parents("div.row")
.siblings("div.p-3.row")
.children("div#reviewContent")
.children()
.text();
$("input#editReviewContent").val(reviewText);
});
</script>
Don't forget to include jQuery.
Also, you can do it with pure javascript. You can easily search the above equivalents on google. This article is a good start!
I'm having an issue with a filter in my angularJS project.
We have a simple draft feature that allows users to save the contents of a large form as a JSON string in our database. They then can go to a section of the site to display and continue working on these forms. I want to provide them a filter on that page to filter by the date they saved the draft on.
Here is my markup:
<div ng-controller="savedFormCtrl" ng-cloak id="saved-form-wrapper"
class="border border-dark border-top-0 border-right-1 border-bottom-1
border-left-1 px-0" ng-init="getSavedForms()"
>
<!-- Search filters -->
<form name="savedFormsFilterWrapper" layout="row" flex="35" layout-align="end center" class="toolbar-search">
<!-- Date filter -->
<md-input-container flex="80">
<div class="text-light font-weight-bold float-left">Filter by saved date:</div>
<md-tooltip style="font-size:1em;">Filter your saved HRTF's</md-tooltip>
<md-datepicker name="dateFilter" class="hrtf-date savedFilterDatepicker"
md-date-locale="myLocale" data-ng-model="savedFormFilters" ng-blur="setFilterDate()"
md-placeholder="" md-open-on-focus
aria-label="Saved forms date filter">
</md-datepicker>
</md-input-container>
</form>
<!-- Saved forms body -->
<div id="savedFormAcc" class="accordion col-md-12 pt-3">
<!-- Accordion item Header -->
<div class="card" ng-repeat="item in savedForms | filter:savedFormFilters">
<div class="card-header savedFormItem" id="savedForm{{$index}}" data-toggle="collapse" data-target="#collapse{{$index}}">
<md-button class="md-raised md-primary" data-toggle="collapse"
data-target="#collapse{{$index}}" aria-expanded="false"
aria-controls="collapse{{index}}"
>
Form Saved on {{ item.savedOn }} - Click to expand
</md-button>
</div>
<!-- Accordion body continues on below -->
</div>
</div>
And my JS:
(function () {
'use strict';
angular.module('hrtf')
.controller('savedFormCtrl', ['$scope', '$window', 'formService',
function savedFormCtrl($scope, $window, formService) {
$scope.savedFormFilters = '';
//Get users's saved forms
$scope.savedForms = {};
$scope.getSavedForms = function(){
formService.getSavedForms()
.then(saved => {
saved.forEach( item =>{
item.data_json = JSON.parse(item.data_json);
});
$scope.savedForms = saved;
return $scope.savedForms;
};
}
]);
})();
Now, the filter works. But whenever The page is loaded, anywhere from 20-50 errors appear, all with the contents Error: [filter:notarray] Expected array but received: {}
All I need to do here is provide a simple filter on a string value to the parent objects savedOn: xxData Herexx value.
What am I doing wrong?
Turns out, I had a similar issue to this post
Basically, my ng-repeat and filter were initializing before the associated model could load. Initializing the model as a blank array and then creating the filter as part of the promise chain did the trick:
//Get users's saved forms
$scope.savedForms = [];
$scope.getSavedForms = function(){
formService.getSavedForms()
.then(saved => {
//Convert and format items here
$scope.savedForms = saved;
$scope.savedFormFilters = { savedOn: ''};
return $scope.savedForms;
}).catch(e => { console.error(e);
});
};
Pretty basic, but I'll leave it here in case it helps someone in the future :)
I have projects and workflows with separate collections.
collections:
Project = new Meteor.Collection("project");
Workflow = new Meteor.Collection("workflow");
After creating project, I am selecting project in the form and displaying Work flow card.
HTML:
<!-- Workflow Card -->
<div id="wCard">
{{#each workflow}}
**<div class="pheader">
<h2>{{project}}</h2>
<hr width="100%">
</div>**
<br>
<div class="workflowcard">
<div class="module-card">
<div class="card-header wfmodule">{{workflowTitle}}</div>
<div class="casting">
<div class="assigned-tag">Assigned To:</div>
<div class="assigned-to">{{team}}<hr></div>
<div class="actions">No Actions Created</div>
</div>
<div class="due">
Due on:
<div>
<div class="day-stamp" >{{weekday d_date}}</div>
<div class="date-stamp">{{date d_date}}</div>
<div class="month-stamp">{{month d_date}}</div>
</div>
</div>
</div>
<div class="btn-box showmuloption">
<button type="edit" class="editw" style="display:none">Edit Workflow</button>
<button type="hide" class="hidew" style="display:none">Hide Actions</button>
<div class="actionBtn"><button class="btn-wf stage-blue-wf button-x-small-wf" id="newAction">New Action</button></div>
</div>
</div>
{{/each}}
</div>
.JS:
Template.workflow.helpers({
getWorkflow: function(){
return Workflow.find();
},
user: function(){
return Meteor.users.find({});
},
getNewaction: function(){
return Newaction.find();
},
});
Now the workflow cards are displaying in a list. I want to display workflows according to projects. If I select a project, the workflow should go to that project, and I create another workflow with same project, it should display in that project. And if I select another project, the workflow should display in that related project.
Please help through this.
I use reactive varrible for this.
At first you need add meteor package:
$ meteor add reactive-var
Your form with project selecting might look like this:
<select id="project" value="{{getProject}}">
{{#each getProjectsList}}
<option id='{{_id}}' value="{{_id}}">{{projectname}}</option>
{{/each}}
</select>
Don't forget create helpers getProject and getProjectsList.
Now it's time for reactive varrible, you can initialise this in onCreated event.
Template.workflow.onCreated(function() {
var instance = this;
instance.projectId = new ReactiveVar(null);
});
When you change selected project, you should change you reactive varrible.
Template.workflow.events({
'change #project': function(){
Template.instance().projectId.set($("#project").val());
});
Every workflow need to have field with project id. You get workflows list like this
{{#each getWorkflows}}
And there is helper for getting workflow's list:
Template.workflow.helpers({
getWorkflows: function() {
var id = Template.instance().projectId.get();
return Workflow.find({projectId: id});
},
...// another helpers
})
So, when you will change project in form, list of workflow also will change, because it depends on reactive var. Also you can sibscribe only needed workflow object, and not all collection.
I hope this will helpfull to someone.
I have a problem with rendering handlebars.js template. I'm doing AJAX request to server, and servers returns me data which contains 'dishes' array with objects.Dish object contains id,price,weight,description,and array of photos. Then i render it with handlebars,and its works properly, 'html' variable containts rendered markup.
var data ;
var modalDishInfo;
var modalDishComments;
var vitrina;
function ajax(params){
$.ajax({
url: '/admin/getDishByCategory',
type: 'POST',
dataType: "json",
data: params,
success: function (result){
data = JSON.parse(result);
vitrina = Handlebars.compile( $('#vitrina_template').html() );
modalDishInfo = Handlebars.compile( $('#modalDishInfo').html() );
var html = vitrina(data.dishes);
console.log(html);
$('.foodmenucontent').empty();
$('.foodmenucontent').append(vitrina(data.dishes));
}
<script id="vitrina_template" type="text/x-handlebars-template">
{{#each this}}
<div class="col-lg-3 mealcard" >
<p class="text-center mealname">{{ dish_name }}</p>
<div class="weightandprice">
<div class="weightcontainer"><span class="mealweight pull-right">{{ dish_weight }} грамм</span></div>
<div class="pricecontainer"><span class="mealprice pull-left">{{ dish_price }} руб.</span></div>
</div>
<button class="orderbutton center-block">ЗАКАЗАТЬ</button>
</div>
{{/each}}
</script>
As you can see this code renders elements, which contains links with openModal() function.I have empty bootstrap modal window and want to render its content, according to clicked link.
function openModal(id){
var foo = id.slice(-1);
var modaldata = data.dishes;
var modaldish = $.grep(modaldata, function (element) {
return element.id == foo;
});
modaldish = modaldish[0];
console.log(modaldish);
var markup = modalDishInfo(modaldish);
$('#modalDishInfo').empty();
$('#modalDishInfo').append(markup);
$('#modalDish').modal('show');
$('.fotorama').fotorama();
};
and template
<script id="modalDishInfo" type="text/x-handlebars-template">
<div class="modalcontainer">
<div class="row">
<div class="col-lg-6">
<div class="fotorama" data-nav="thumbs" data-width="100%" data- thumbwidth="80" data-thumbheight="45"
data-transition="crossfade" data-loop="true" data-keyboard="true" data-navposition="bottom"
data-fit="cover" data-ratio="1600/900">
{{#each dish_photos}}
<img src="/uploads/gallery/{{ this.path }}" class="img-responsive" alt="">
{{/each}}
</div>
</div>
<div class="col-lg-6">
<p class="mealname">{{ dish_name}}</p>
<pre>{{ dish_description }}</pre>
<p>{{ dish_weight }}гр.</p>
<p class="mealprice">{{ dish_price }}руб.</p><br>
<button class="orderbutton ">ЗАКАЗАТЬ</button>
</div>
</div>
The problem is second template(modalDishInfo) dont want to render, console.log returns 'markup' variable completely empty. I tried different combinations of block helpers, and expressions,but none of them working. Maybe im missing something important? Or need to use specific expressions, when passing single object to template?
I found mistake that i did.My template id and container id(which is empty) are the same. So jquery selector returned me empty markup. I didn't notice that, because im using TWIG and my scripts was in {% verbatim %} tag to avoid TWIG errors, so i dont receive any errors or warning using duplicate ID's in code. Hope my answer is informative and can be helpful to someone.
I have a rather sophisticated template for Kendo ListView using knockout-kendo.js bindings. It displays beautifully. My problem is that I need to use the visible and click bindings in parts of the template, but I can't get them to work. Below is a simplified version of my template. Basically, deleteButtonVisible determines whether the close button can be seen, and removeComp removes the item from the array.
<div class='template'>
<div >
<div style='display:inline-block' data-bind='visible: deleteButtonVisible, event: {click: $parent.removeComp}'>
<img src='../../../Img/dialog_close.png'></img>
</div>
<div class='embolden'>#= type#</div><div class='label1'> #= marketArea# </div>
<div class='label2'> #= address# </div>
<!-- more of the same -->
</div>
The view model:
function CompViewModel() {
var self = this;
self.compData = ko.observableArray().subscribeTo("compData");
self.template = kendo.template(//template in here);
self.removeComp = function (comp) {
//do something here
}
}
html:
<div class="row" >
<div class="col-md-12 centerouter" id="compDiv" >
<div class="centerinner" id="compListView" data-bind="kendoListView: {data: compData, template: template}"></div>
</div>
</div>
finally, sample data:
{
type: "Comparable",
marketArea: "",
address: "2327 Bristol St",
deleteButtonVisible: true
},
Take in count that the deleteButtonVisible must be a property on the viewModel linked to the view.You are not doing that right now. The click element can v¡be access from the outer scope of the binding and remove the $parent.He take the method from the viewmodel. Take in count that every thing that you take on the vie must be present on the view model for a easy access.
