Unable to call @getCollection("partials") from docpad.coffee

[patocallaghan]

Hey,

I've come across an issue where it seems that I can't define a collection in my docpad.coffee that tries to access partials e.g. @getCollection('partials').

By chucking in some debug statements it seems that the functions for the collections in docpad.coffee are running before PartialsPlugin.populateCollections is called so it's always undefined. But instead if I call @getCollection from within one of my documents it works fine.

//Fails in docpad.coffee, returns undefined
collections:
     objects: ->
            @getCollection("partials").findAllLive({isObject:true})

//Works okay in index.html.eco
<% for object in @getCollection("partials").findAllLive({isObject:true}).toJSON(): %>

I've attached a debug log here.

If you want to replicate the issue it's occurring on my repo here. You'll just have to uncomment the collections in docpad.coffee.

Thanks,
Pat

Could be that the partials plugin hasn't been able to create the partials plugin yet. However, you can change your query to @getCollection('html').findAllLive(isObject:true, partial:true) - does that work? As the partials plugin should inject partial:true into the in memory meta data for all the partials :)

Are you saying to add that into the docpad.coffee or the .eco file?

Adding the suggested statement runs without any errors in docpad.coffee unlike the original query, but when I run @getCollection('objects') within my .eco file it comes back empty.

Actually, I've just tried it and running that query in my .eco comes back empty anyway.

Sorry I mustn't have been clear enough.

docpad.coffee

collections:
     objects: (database) ->
            database.findAllLive({partial:true, isObject:true})

index.html.eco

<% for object in @getCollection("objects").toJSON(): %>

That didn't seem to make a difference either..See the branch I have here with those changes. index.html.eco is in src/documents.

I am having the exact same Problem here. I tried to get a collection of all partials with the metatag "isObject"

collections:
     docu: (database) ->
                 database.findAllLive({partial:true, isObject:true})

and call it within a template that uses the paged plugin. This Plugin expects a collection name

---  
pagedCollection: 'docu'
---

Console returns undefined for me

Not exactly the same use case, but seems a related issue with the partials plugin.

From within a partials/header.html.md.eco file (template for a reusable contextual site menu), we run a query as follows:

<ul>
    <% for page in @getCollection("menu").toJSON(): %>
        <li class="<%= if page.id is @document.id then 'active' else 'inactive' %>">
            <a href="<%= page.url %>">
                <%= page.title %>
            </a>
        </li>
    <% end %>
</ul>

Then we use this partial in a default.html.eco layout:

<%- @partial('header.html.md.eco')%>

Unfortunately it outputs: TypeError: Object # has no method 'getCollection'. And in the logs: warning: Something went wrong while rendering: header.html.md.eco.

When we do the same not from within a partial, but right away in the layouts/default.html.eco file , then there is no problem, and we get the desired output.

Update: Adding @ (~ this) solved it: <%- @partial('header.html.md.eco', @)%> (cfr #3 (comment)).
