Why is my attempt to fetch and show MongoDB documents in my Meteor app crashing?
I'm trying to fetch and display some MongoDB documents in my Meteor app. I am trying to use the docs here as a basis for this.
The HTM I've added is this:
{{> placesLived}}
. . .
<template name="placesLived">
<table style="width:60%">
{{#each places}}
<tr>
<td>{{ts_city}}</td>
<td>{{ts_state}}</td>
<td>{{ts_yearin}}</td>
<td>{{ts_yearout}}</td>
</tr>
{{/each}}
</table>
</template>
...so that the entire .html file is now this:
<head>
<title>timeandspace</title>
</head>
<body>
<h1>A List of the Places I Have Lived</h1>
{{> addTimeSpaceForm}}
{{> placesLived}}
</body>
<template name="addTimeSpaceForm">
<form>
<label for="city">City</label>
<input type="text" name="city" id="city">
<br/>
<label for="state">State</label>
<input type="text" name="state" id="state">
<br/>
<label for="yearin">Year Arrived</label>
<input type="text" name="yearin" id="yearin">
<br/>
<label for="yearout">Year Departed</label>
<input type="text" name="yearout" id="yearout">
<br/>
<input type="submit" name="insertdocument" id="insertdocument" value="Add Place Lived">
</form>
</template>
<template name="placesLived">
<table style="width:60%">
{{#each places}}
<tr>
<td>{{ts_city}}</td>
<td>{{ts_state}}</td>
<td>{{ts_yearin}}</td>
<td>{{ts_yearout}}</td>
</tr>
{{/each}}
</table>
</template>
The Javascript I've added is this:
Template.placesLived.helpers({
places: function () {
// this helper returns a cursor of all of the documents in the collection
return TimeAndSpace.find();
}
});
...so that the entire .js file is now this:
TimeAndSpace = new Mongo.Collection('timeAndSpace');
if (Meteor.isClient) {
Template.addTimeSpaceForm.events({
'submit form': function(event){
event.preventDefault();
var city = event.target.city.value;
var state = event.target.state.value;
var yearin = event.target.yearin.value;
var yearout = event.target.yearout.value;
Meteor.call('insertLocationData', city, state, yearin, yearout);
}
});
}
if (Meteor.isServer) {
Meteor.startup(function () {
// code to run on server at startup
});
Meteor.methods({
'insertLocationData': function(city, state, yearin, yearout){
console.log('attempting to insert a record');
TimeAndSpace.insert({
ts_city: city,
ts_state: state,
ts_yearin: yearin,
ts_yearout: yearout
});
}
});
}
Template.placesLived.helpers({
places: function () {
// this helper returns a cursor of all of the documents in the collection
return TimeAndSpace.find();
}
});
My notion of what is supposed to happen here is that the "placesLived" template is added to the page, which template calls the "places" function in the js file -- which returns all the TimeAndSpace documents -- and finally the "placesLived" template loops through those returned documents, placing each field in a "td"
However, saving these changes (which restarts the Meteor app) wreaks havoc in the Meteor field: the command prompt cast the following aspersions (not to be confused with asteroids) on me:
The Meteor machine is obviously not amused. What have I fouled in my code / what needs to change?
Your helper is running on the client & server. Put an isClient around it & you'll be fine.
Anytime you get pretty purple/blue colors on the console it means something is wrong with your server. When it says Template is not defined that tells you the server can't find something called Template.
