Linked entries/assets not resolved on preview mode

[martzoukos]

Edit 16.12.2016: Apologies for the initial confusing title, I had a mixed up impression of what dynamic_entries do, the issue is the same but it has to do with linked entries/assets not being resolved, so please ignore what mention to dynamic_entries I make.

---

Hello there,

I'm using the with_preview method to preview a specific page that has linked assets and entries in some of its fields.

While the nonlinked fields are working correctly, the ones where an asset or another entry is referenced, are not being fetched, for example:

with_preview(space: 'CONTENTFUL_SPACE', access_token: 'CONTENTFUL_ACCESS_TOKEN' ) do |preview|
   @article = preview.entry('ENTRY_ID')
end

...

@article.inspect:

{
    ...
    [:post_category, "Article"],
    [:main_image, #"Link", :linkType=>"Asset", :id=>"C6y5BNKNYOUaUIIm2ccqU"}>] 
    ...
}

I've snooped into the gem's code a bit and I saw that dynamic entries are set to :auto so this should be getting all the linked stuff.

Is this the intended behaviour? If not I can make a recursive method to fetch all the stuff, but I wanted to check first before I do it.

Thanks again!

Hey @martzoukos,

Let me take a look into this, haven't experienced this issue before.

Hey @martzoukos,

Found the issue, you're using client.entry which uses the /entries/entry_id endpoint which doesn't resolve includes. Instead, you should be using /entries?sys.id=entry_id and fetching the first element of the collection. Difference is that the #entries endpoint does have includes resolution.

Hope that helps.

Cheers

Thanks David,

so I need to do something like that?

with_preview(space: 'CONTENTFUL_SPACE', access_token: 'CONTENTFUL_ACCESS_TOKEN' ) do |preview|
   @article = preview.entries('ENTRY_ID').first
end

with_preview(space: 'CONTENTFUL_SPACE', access_token: 'CONTENTFUL_ACCESS_TOKEN' ) do |preview|
   @article = preview.entries('sys.id' => 'ENTRY_ID').first
end

Cheers

Ah, apologies. I should have looked here first.

The object I'm fetching in this way, though, has a different schema than the content that's saved in my .yml files.
For example, if a content item has an image field, this is saved in the data folder as:

:image:
  :url: "//images.contentful.com/..."

so I can then access it in my view as

article.image.url

When I switch to the Preview API, though, then I need to change my code to access the same property:

article.main_image.fields[:file].url

If I want to easily switch between production and preview mode in a view, this makes it very hard, if not impossible to access the properties in the same way. Is there any way to work around this?

Thank you again.

Hey @martzoukos,

You can do main_image.image_url I know it's a bit different from the middleman API, I will add a patch release adding an alias for image_url to be url so this is no longer an issue.

Cheers

Update: The PR has been created, you can follow up here: contentful/contentful.rb#112

[dlitvakb]

Release v1.2.0 of contentful.rb has been done, this will allow you to use main_image.url.

Cheers
