I'm practicing with Meteor and I can't understand why the remove function of a MongoDB collection doesn't work. This is my html template where I created a button to remove the news:
<template name="news">
<h2>News</h2>
<form>
<input type="text" name="title" placeholder="Add some news">
<button>Add</button>
</form>
<ul>
{{#each News in showNews}}
<li>{{News.title}}<button class="removeAction">×</button></li>
{{/each}}
</ul>
</template>
And this is my client.js file where I created the event to execute the remove function:
Template.news.events({
'submit form': function(e) {
e.preventDefault();
var title = e.target.title.value;
News.insert({ title: title, createdAt: new Date() });
e.target.title.value = "";
},
'click .removeAction': function(e, a) {
News.remove(this._id);
}
});
I can't really understand why it doesn't work, I tried a lot of changes but nothing worked, when I click the "X" button nothing is happening.
Most probably the issue is that this._id is not defined. I think you are not using blaze the correct way. I'm not a blaze user but I think this will work.
<template name="news">
<h2>News</h2>
<form>
<input type="text" name="title" placeholder="Add some news">
<button>Add</button>
</form>
<ul>
{{#each showNews}}
{{> newsPost}}
{{/each}}
</ul>
</template>
<template name="newsPost">
<li>{{title}}<button class="removeAction">×</button></li>
</template>
And your removeAction event listener should look like this.
Template.newsPost.events({
'click .removeAction': function(e, a) {
News.remove(this._id);
}
});
