I have a {{#each}} that's essentially iterating through the users collections. I now wish to check if the user is an admin to set a switch (materialize). A simplified version:
{{#each getUsers}}
testing: {{_id}} {{#if isAdmin "tTEScMyjCedano2oT"}}checked="checked"{{/if}}
{{/each}}
Here I am hard coding in the _id parameter in the {{#if}} and it works as expected. The isAdmin function works correctly, the {{#if}} works and the {{_id}} works as well (prints out the correct id).
But of course I do not want to hard code the id passed to isAdmin but want it to be {{_id}} however it doesn't work. i.e.
{{#each getUsers}}
testing: {{_id}} {{#if isAdmin "{{_id}}"}}checked="checked"{{/if}}
{{/each}}
does not work and neither does
{{#each getUsers}}
testing: {{_id}} {{#if isAdmin "{{../_id}}"}}checked="checked"{{/if}}
{{/each}}
nor
{{#each getUsers}}
testing: {{_id}} {{#if isAdmin {{id}}}}checked="checked"{{/if}}
{{/each}}
What is the correct way to do this?
Don't use double quotes nor curly braces :
{{#each getUsers}}
testing: {{_id}} {{#if isAdmin _id}}checked="checked"{{/if}}
{{/each}}

I have collections like this:
I want to iterate over object.questions.teema for example.
I have helper:
Template.game.helpers({
theGame: function() {
var theGame = Game.findOne({_id:"LhQmaZKW8eJNenyX9"})
console.log(theGame)
return theGame
}
});
and template:
<template name="game">
{{#with theGame}}
{{#each theGame.questions}}
{{teema}}
{{/each}}
{{/with}}
</template>
But it doesnt work, what is wrong with the template?
'#each theGame.questions' Will not work inside the #with, because you can access the 'theGame' object directly.
The point is when you try to get theGame object inside the #with it will return you undefined, because 'theGame' object does not have theGame property, Which you want to access inside #with block.
<template name="game">
{{#with theGame}}
{{#each questions}}
//Thie #each because you have nested array. As I can see in your console log.
{{#each this}}
{{teema}}
{{/each}}
{{/each}}
{{/with}}
</template>
What is {{teema}} supposed to be?
Regardless, as you can see from your console.log statement, {{theGame.questions}} returns another array. But that array returns objects. This is really hard to query for with Blaze.
The better solution would be to flatten it out so that your data is shaped like this:
questions: [
{
a: 'asdfkjah',
level: 'askdjfhal',
q: 'asdkfh',
teema: 'asdkfjh'
vaartus: 100
},
{
...
}
]
This way you don't have an array nested in an array. That will allow you to:
{{#with theGame}}
{{#each theGame.questions}}
{{this.teema}}
{{/each}}
{{/with}}
theGame.questions is an array (that you iterate over) of array of objects which have the teema key. So you still need to iterate over the 2nd level array, or define a specific item in that array before you can eventually reach the object with teema property.
Maybe something like:
{{#with theGame}}
{{#each questions}}
{{#each this}}
{{this.teema}}
{{/each}}
{{/each}}
{{/with}}
But it depends on why you have these 2-level arrays in the first place.
I have nested each and want to use parent this value.
{{#each county}}
Country name : {{this}}
{{#each state}}
{{this}} is one of the state of {{country}} //here how to use country
{{/each}}
{{/each}}
I have tried {{../this}} but it shows
Can only use `this` at the beginning of a path.
Instead of `foo.this` or `../this`, just write `foo` or `..`.
simply you can do
{{#each county}}
Country name : {{this}}
{{#each state}}
{{this}} is one of the state of {{..}} //here how to use country
{{/each}}
{{/each}}
see {{..}}
EDIT: edited answer
I'm currently making a simple web app with meteor.js . I'm trying to implement a simple feature for my fantasy football league's custom site that I'm building.
Here's my code that's not working.
{{#each users}}
{{#if Meteor.userId() {{_id}} }}
{{> ownTradingBlock}}
{{else}}
{{> userTradingBlock}}
{{/if}}
{{/each}}
So basically I want to render a different template if the user in the list of league members is the current user that is logged in. Does anybody have any thoughts on how this is creating an error, and/or if there's a better way to do it?
Here's the error code I'm getting.
.html:67 : expected space
You cannot use a Meteor method within Spacebars. For this you will need to create a helper:
Template.yourTemplate.helpers({
isEq: function (id) {
if (Meteor.userId() === id)
return true;
return false;
}
});
Then in your template:
{{#each users}}
{{#if isEq _id}} }}
{{> ownTradingBlock}}
{{else}}
{{> userTradingBlock}}
{{/if}}
{{/each}}
I have the following simplified document:
{
channel:'Channelname',
users: [
{userId:1},
{userId:2},
{userId:3}
]
}
How can i access the userId's in a {{#each}} loop like so:
{{#each channels}}
{{channel}}
{{#each channels.users}}
{{userId}} //or {{channels.users.userId}} ?
{{/each}}
{{/each}}
The first {{#each}} loop prints my channelname as expected, but the second {{#each}} loop doesn't print anything.
Regards, Cid
Use
{{#each channels}}
{{channel}}
{{#each users}}
{{userId}}
{{/each}}
{{/each}}
When going into an each loop, handlebars will use the key names in the array directly.
What is the standard way to access outer #each collection values in the loop?
for example:
<template name="example">
{{#each outerCollection}}
<tr>
{{#each innerCollection}}
<td>{{aaa}}</td>
{{/each}}
</tr>
{{/each}}
</template>
Template.example.aaa = function(){
// cannot access outerCollection values
}
in above Template.example.aaa, this points to the inner collection.
I cannot find way to access outerCollection items.
My solution is like below, I am defining my own helper function.
Is it a standard Meteor way to achieve this purpose?
<template name="example">
{{#each outerCollection}}
<tr>
{{#each innerCollection}}
<td>{{myHelper ../outerItem innerItem}}</td>
{{/each}}
</tr>
{{/each}}
</template>
Handlebars.registerHelper('myHelper', function (outItem, inItem) {
// can access outerCollection via outerItem
});
I found a similar question for the case of inner event handler access.
I think you've answered this yourself! Using ../ is documented in https://github.com/meteor/meteor/wiki/Handlebars.
You can use below code to fetch outer collections.
suppose you have collection called as Collection.Customer and Collection.RechargePlan and you are using both in a template for updating Customer.
Customer = {"name":"James", "rechargeplan":"monthly"};
RechargePlan = [{"rechargeplan": "monthly"},{"rechargeplan": "yearly"}];
//Inside template, Bydefault Customer is available.
{{#each RechargePlan}}
{{#if equals ../rechargeplan rechargeplan}}
//Hurray Plan matches
{{/if}}
{{/each}}
In above code, ../rechargeplan is actually Customer.rechargeplan, ../ actually went one step above heirarchy and then accessed the field if available, since Customer is already available to template, it's field is picked up.
