I'm trying to get access to the parent div or any div via an helper i set up in meteorjs.
For instance how can i get the div with a class of "form-group" for the isRegion helper ?
<div class="form-group">
<div class="col-md-4">
<select name="{{regionsPart.name}}" type="select" class="form-control fields regionsField">
{{#each regions}}
{{#if isRegion}}
<option class="choiceRegion" value="{{region}}" selected>{{region}}</option>
{{else}}
<option class="choiceRegion" value="{{region}}">{{region}}</option>
{{/if}}
{{/each}}
</select>
</div>
Template.mytemplate.helpers({
'isRegion' : function(){
var parentData = Template.parentData(1)
var regions = Session.get('regions')
var region = this.region;
console.log($(this) trying to get the parent div for further use )
)}
Thank you very much.

I’m trying to have a reactive bootstrap selectpicker but I have a weird behaviour:
An event has to change the options of the select but it works only after the first event which is not working because the app doesn’t go into the onRendered part…
This is the onRendered part:
var renderTimeout = false;
Template.printerselect.onRendered( function(){
if (renderTimeout !== false) {
Meteor.clearTimeout(renderTimeout);
}
renderTimeout = Meteor.setTimeout(function() {
$('#printerName').selectpicker("refresh");
renderTimeout = false;
}, 10);
});
Template.printerSetupForm.onRendered( function(){
$('.selectpicker').selectpicker();
});
here, the templates :
<div class="col-lg-3 col-md-4 col-xs-12 form-group">
<label>COMPANY</label>
<select id="printerCompany" class="form-control selectpicker" name="printer[company]">
<option selected="true" disabled="disabled" value={{company}}>
Please Select A Printer Company
</option>
{{#each Companies}}
<option value="{{company}}" {{printerCompanySelected company}}> {{company}}</option>
{{/each}}
</select>
</div>
<div class="col-lg-3 col-md-4 col-xs-12 form-group">
<label>PRINTER NAME</label>
<select id="printerName" class="form-control selectpicker" name="printer[name]">
<option selected="true" disabled="disabled" value={{name}}>
Please Select A Printer
</option>
{{#each Names}}
<!--<option value="{{name}}" {{printerNameSelected name}}>
{{name}}
</option>-->
{{>printerselect}}
{{/each}}
</select>
</div>
<template name="printerselect">
<option value="{{name}}"> {{name}} </option>
</template>
The refresh is called when the page is rendered.
Then I change the company which changes some Session variables and reactively to change the name select options but the refresh is not called so that doesn’t come to the onrendered part.
But when I change again the company it’s working, the onRendered part is called.
Weird thing is that even if this is not displaying the right names, when i’m choosing a name which doesn’t match with the company, the select chooses the right one.
Sorry for my english in advance, I did my best.
Thanks you in advance !
EDIT: Names helper :
Names: () => {
company=Session.get('printer').company;
if(typeof company!='undefined') {
return Printers.find({company: company}).fetch();
} else {
return Printers.find().fetch();
}
}
I set the Session variable 'printers' with an empty field. When I select a company, it's now working but without company, I don't get any printers because I don't have to test company with 'undefined' but with empty field.
So I changed to test with empty field and it isn't working anymore...
So weird that a test could cancel a onRendered, this must be an issue with the Mongo stuff.
I will continue to search on it.
How can I use a variable in a scope up from the current scope in Blaze?
For example:
<template name="userLayoutEditCreate">
{{#each findUser id}}
<h3>I am a single user (edit/create)</h3>
<h3>{{id}}</h3>
<form action="/" method="post">
<fieldset>
<!-- Primary instruments multi-select -->
<div class="form-group">
<label class="control-label" for="playerPrimaryInstrument">Primary instruments</label>
<div class="controls text-left">
<select id="playerPrimaryInstrument" name="playerPrimaryInstrument">
{{#each instruments}}
<option value="{{name}}" {{#if equals primary_instrument name}} selected="selected" {{/if}}>{{name}}</option>
{{/each}}
</select>
</div>
</div>
</fieldset>
</form>
{{/each}}
</template>
The if statement does not run within the each block. But it does run outside of the each block (I have defined the helper).
The error I get looks like this.
Reactive HTML attributes must either have a constant name or consist of a single {{helper}} providing a dictionary of names and values. A template tag of type BLOCKOPEN is not allowed here.
==== EDIT ====
Even using the '../' scope definition didn't work in this case. What DID work was putting the expression inside the value of the selected attribute. I'm not sure why that is, please let me know if you have any idea?
The solution:
{{#each instruments}}
<option value="{{name}}" selected="{{#if equals name ../primary_instrument}} selected {{/if}}">{{name}}</option>
{{/each}}
Try this:
{{#if equals ../primary_instrument name}}
{{/if}}
I'm stumped as to why part of my code isn't displaying when the session variable is set to true. When the user selects a certain option from the dropdown, based on the value, it changes the warmerselected to TRUE. I have tracked this in the console, and it works just fine.
Here is my code:
HTML:
<div class="item">
<div class="ui label">Product Type:</div>
<select id="ProductType" name="ProductType">
{{#each ProductTypes}}
<option value="{{ProductTypeAbbrev}}">{{ProductTypeName}}</option>
{{/each}}
</select>
</div>
{{#if warmerselected}}
<div class="item">
<div class="ui label">Name:</div>
<input type="text" name="ProductName" placeholder="Enter Product Name">
</div>
{{/if}}
JS:
Session.setDefault("warmerselected", false);
Template.addProduct.events({
'change #ProductType': function (e) {
var selitem = $("#ProductType").val();
if(selitem == "WA") {
Session.set("warmerselected",true)
}else {
Session.set("warmerselected",false);
}
}
});
Template.addProduct.helpers({
warmerselected: function(){
return Session.get("warmerselected");
}
});
Session isn't meant to be helper in HTML, you have to create one
I have two Collection : a collection A which include array of B ids.
Template A :
<template name="templateA">
Name : {{name}} - {{_id}}
{{#each allBsOfThisA}}
{{> Bdetail}}
{{/each}}
Add B for this A
</template>
Note : in this templateA, I list all A and their detail informations. At bottom of the A, I putted a link to add a B.
Template of Bsubmit :
<div class="form-group {{errorClass 'nameOfB'}}">
<label class="control-label" for="nameOfB">nameOfB</label>
<div class="controls">
<input name="nameOfB" id="nameOfB" type="text" value="" placeholder="nameOfB" class="form-control"/>
<span class="help-block">{{errorMessage 'nameOfB'}}</span>
</div>
</div>
<input type="submit" value="Submit" class="btn btn-primary"/>
On the Bsubmit script : I want to get the ID of A. I tried with template.data._id but it's not working :
Template.Bsubmit.events({'submit form': function(e, template) {
e.preventDefault();
console.log("template.data._id: " + template.data._id);
var B = {
name: $(e.target).find('[name=name]').val(),
AId : template.data._id
};
}
});
EDIT :
BSubmit's iron-router part :
Router.route('Bsubmit ', {name: 'Bsubmit '});
Neither the template nor the route does know about the A-instance of the other template/route.
So one solution would be to pass the id to the route, which allows you to fetch the instance or use the id directly:
Template:
<template name="templateA">
Name : {{name}} - {{_id}}
{{#each allBsOfThisA}}
{{> Bdetail}}
{{/each}}
Add B for this A
</template>
Route:
More information about passing arguments to a route
Router.route('/Bsubmit/:_id', function () {
var a = A.findOne({_id: this.params._id});
this.render('Bsubmit', {data: a});
});
Then you could use template.data._id in the event.
Another solution would be to embed the form into the other view, so you can access the data of the parent template in there (documentation of parentData).
i'm trying to filter my collection on dropdownlist change , here's my code in the template manager
Template.postsList.events({
"change .typeselection": function(e, t){
console.log("drop changed");
return Session.set("type", $("[name=type]").val());
}
});
here's my template code :
<template name="postsList">
<select name="type" id="type" value="" placeholder="type the adress" class="form-control typeselection">
<option value="Restaurant">Restaurant</option>
<option value="Hotel">Hotel</option>
<option value="Shop">Shop</option>
</select>
<div class="posts">
{{#each postsWithRank}}
{{> postItem}}
{{/each}}
{{#if nextPath}}
<a class="load-more" href="{{nextPath}}">Load more</a>
{{else}}
{{#unless ready}}
{{> spinner}}
{{/unless}}
{{/if}}
</div>
</template>
From my understanding,this code works for you
//on dropdown change we are setting the new value in session
Template.postsList.events({
"change .typeselection": function(e, t){
console.log("drop changed");
Session.set("type", $("[name=type]").val());//no need to return anything here
}
});
//whenever the session variabe changes this code will re run
Template.postsList.helpers({
"postsWithRank": function(){
//assuming you have type field in your collection and you want filter on that field
return Posts.find({"type":Session.get("type")});
}
});
//so this code will display the selected relative data
{{#each postsWithRank}}
{{> postItem}}
{{/each}}
