I have a Product model with a jsonb column :images to store Carrierwave images.
When trying to edit the product from rails admin, I get the following error:
undefined method `url' for #<Array:0x0000560faa6cefe8>):
Any idea of why am I getting this? It's driving me crazy.

def set_importattribute
#importattribute = Importattribute.find(params[:id])
end
Why is Rails looking up in PG importattribute_id instead of id ?
This is also occuring in the test suite & I am quite puzzled by it.
I'm trying to use the pg_search gem in my rails application to search through numerous models from one search bar.
I have added the search bar:
<div id="search-bar">
<%= form_tag searches_path, method: :get do %>
<span><%= text_field_tag :query, params[:query] %><%= submit_tag "Search", name: nil %></span>
<% end %>
</div>
The route:
resources :searches
The searches controller index method:
def index
#results = PgSearch.multisearch(:query)
end
And the search index.html.erb:
<ul>
<% #results.each do |result| %>
<li><%= link_to result.searchable.title, result.searchable %></li>
<% end %>
</ul>
Each model that I want to be searchable has something like this in it:
include PgSearch
multisearchable :against => [:content, :author]
And I have an initializer like this:
PgSearch.multisearch_options = {
:using => {
:tsearch => {
:dictionary => "english"
}
}
}
I created a new item to make sure that it was added to the pg_search_documents table and checked the terminal to see that it was.
Yet when I enter a search query, nothing is coming up in the results table?
Here is the terminal output from the search:

Did you do the following?
$ rails g pg_search:migration:multisearch
$ rake db:migrate
It's required for multisearching. Also existing items may not be added to the document as you already know. You would need to "rebuild" as stated in the docs. When you made a new item for testing, did you save it properly?
Here are the docs I found for the pg gem:

When I enter an incorrect track_id in url for example : tracks/123456
=> it returns 404 not found as expected !
If I try with incorrect challenge_id which is one of my other model : tracks/1/challenges/12345
=> it return null instead of 404 not found.
The code of both seems to be the same so I can't found the issue.
If you could help me to found why I get null instead of 404, seeing the code below :
routes.rb
resources :tracks do
resources :challenges do
resources :ressources
end
end
challenges_controller.rb
def show
render json: #challenge, include: [:ressources, :challenges_startups]
end
private
def set_challenge
#track = Track.find(params[:track_id])
#challenge = #track.challenges.where(id: params[:id]).first
end
tracks_controller.rb

render json: #track, include: [:challenges]
end
private
def set_track
#track = Track.find(params[:id])
end

You have defined #challenge like below
#challenge = #track.challenges.where(id: params[:id]).first
where returns nil if there is no record matching the condition. That is why you get null instead of 404 not found.
Whereas find in contrast returns 404 not found if the record doesn't exist.
If you want to get 404 not found, then modify #challenge like below
#challenge = #track.challenges.find(params[:id])
I have a next button that is working great, but previous button just does not want to play nice. Funny thing is that I've tried to build this a few different ways referencing methods on SO and elsewhere, but previous always goes to the earliest record...
In my submission model:
def previous
self.class.first(:conditions => ["created_at < ?", created_at], :order => "created_at asc")
end
def next
self.class.first(:conditions => ["created_at > ?", created_at], :order => "created_at asc")
end
And in my view:
<% if #submission.previous %>
<%= link_to "previous", contest_submission_path(#contest, #submission.previous),
:class => 'pull-left btn btn-large' %>
<% end %>
<% if #submission.next %>
<%= link_to "next", contest_submission_path(#contest, #submission.next),
:class => 'pull-right btn btn-large' %>
<% end %>
Like I said, next works great, but previous returns to the earliest record. I'm nearing wits end with this one. Anybody have an answer?

<% if #submission.next_sub %>
<%= link_to "next", contest_submission_path(#contest, #submission.next_sub),

I ended up exchanging the names of the methods, so that the show record order would match the index, which is scoped in DESC order or most recent to earliest.
Your code is correct, but your log shows
SELECT "submissions".* FROM "submissions"
WHERE (created_at < '2012-10-08 14:32:40.590930')
ORDER BY submissions.created_at ASC, created_at asc LIMIT 1
If this is a query that searches for previous, this is where it fails (because it orders the previous dates in ascending order, and takes the first - the earliest). Could it be you forgot to restart the app after making changes (though it should be reloaded automatically in dev mode)?
Or it is possible you have default_scope or some other scope that breaks the conditions. I wonder why there is submissions.created_at ASC, created_at asc - twice? Probably submissions.created_at ASC is a default scope.
I'd suggest you to use new AR query syntax, and perhaps reorder to exclude other ordering scopes:
self.class.where("created_at < ?", created_at).reorder("created_at desc").first
I built a feature in my app to allow users to search for images that would search the image description,member who uploaded it, and image tags but I have this weird issue where if I search for the name 'jason' it breaks, but a name like 'jesse' works just fine.
Here is my controller
def search_results
#tattoos = Tattoo.where("description LIKE ?", "%#{params[:search]}%") | Tattoo.tagged_with("#{params[:search]}", :any => true ) | Member.where("membername LIKE ?", "%#{params[:search]}%").order("created_at DESC").page(params[:page]).per(10)
end
if i search for 'jason' my app breaks, giving me an 'undefined method' error and the console shows a bunch of stuff not shown if I searched for say, 'jesse'. Im not entirely sure how to word that but here is what I mean.

The "| vs ||" issue is not your problem. Doing this:
Tattoo.where(...) | Tattoo.tagged_with(...) | Member.where(...)
will result in an array that is the union of the three input results. Switching to ||:
Tattoo.where(...) || Tattoo.tagged_with(...) || Member.where(...)
will just give you Tattoo.where(...) since that query will never be false or nil and the || will short circuit as soon as it has non-falsey result; Tattoo.where(...) might might be empty but empty and falsey are different things.
Your problem is that you're mixing two different things in one array: Tattoo instances from the first two queries and Member instances from the last query. Then your ERB assumes that everything in #tattoos is a Tattoo (or something else that responds to member):
<% #tattoos.each do |t| %>
<% unless t.member.nil? %>
If your Member.where(...) finds anything, then you will have at least one Member instance in #tattoos and there is no Member#member method as the error message indicates:
ActionView::Template::Error (undefined method `member' for #<Member:0x007f0b0ca077b0>):
Stop mixing two different classes in #tattoos and your problem should go away. Or you could rename it to, say, #matches and smarten up your view logic to be able to display both Tattoo and Member instances.
One thing I noticed is that you are using | instead of || in
#tattoos = Tattoo.where("description LIKE ?", "%#{params[:search]}%") | Tattoo.tagged_with("#{params[:search]}", :any => true ) | Member.where("membername LIKE ?", "%#{params[:search]}%").order("created_at DESC").page(params[:page]).per(10)
perhaps that might be part of the issue?
I would also argue that you should move this logic into the model, which should make it easier to test.
# Controller
#search_results = Tattoo.results_for_search(params[:search])
#search_results << Member.results_for_search(params[:search])
# Tattoo Model
def results_for_search(search_term)
results = where("description LIKE ?", search_term).all
results << tagged_with(search_term, :any => true)
end
