I have this rule:
match '*urlnames' => 'home#searching_names'
The URL address looks like website.com/john.html.
The problem is, that in the log I see
Parameters: {"urlnames"=>"john"}
without the .html extension. Text extension is important, I would need to test it in the controller.
I tried to add to the routing rule this part:
match '*urlnames' => 'home#searching_names', :defaults => { :format => "html" }
But still the same, in the log is
Parameters: {"urlnames"=>"john"}
How can I catch the extension in the controller?
You have access to the requested format via request.parameters[:format] or (as a MIME type) via request.format.
However, you can also use a respond_to block:
def show
file = params[:urlnames]
respond_to do |format|
format.html { ... }
format.txt { ... }
end
end
where ... is code to render some text, or send some data or a file.
If you're just trying to show some static files, just place them in the public dir, and bypass Rails entirely.

I am trying to upload a file using dropzone. When the file is uploaded, I want to redirect the page to root url. When I upload the file, the request is sent and the response is in json format. I have in my controller:
respond_to do |format|
format.json{ render :json => { :location => root_url, :flash => {:success => "The file was uploaded successfully"} }}
end
Can please anyone help me with what is wrong with my respond_to block?
This json response will not in itself redirect, as it responds with json to (presumably) an ajax request. When the response comes back, the client will need to do something with that response, such as set window.location to the :location attribute.
ie in the success callback of the dropzone request
Rails drive me crazy. I'm trying to respond to with an action with JSON.
My goal is to let be the JSON the only format for a response to a URL.
Let's see some code.
The Model is a Devise user, with some added field.
The Controller is my UsersController that has this action
# /app/controllers/users_controller.rb
def static
render json: current_user
end
I got also this jbuilder view
# /app/views/users/static.json.jbuilder
json.content format_content(#user.content)
json.author do
json.name #user.name
json.email_address #user.email
end
if current_user.admin?
json.someValue "foo"
end
this View doesn't do some interesting stuff, but It's just a try.
Anyway I'll never get the static.json.jbuildercontent. I always get all Devise user's content as a JSON.
Am I doing something wrong? (or better: where I done the epic fail?)
Anyway found the solution:
# /config/route.rb
get 'my-static-json' => 'mycontroller#static', defaults: {format: :json}
# /app/controllers/mycontrollers_controller.rb
def my-static-json
end
# /app/views/mycontrollers/my-static-json.json.jbuolder
json.content "some static content"
this is only an example but gives have all the information that I needed
Noob
How should I send a single string variable to another site from my rails app? ie the outside service sends a get request to my controller/route and then the controller must respond with the string (and I assume a response code). The string is intended to be added to their html code.
In my controller should I
render :text => "string"
or
respond_with("string) #as xml or json
or something completely different?
Just try the following code. Here your application gives the text and json as per the request.
respond_to do |format|
format.json do
render :json => 'string'
end
format.html do
render :text => 'string'
end
end
I would like to use link_to to call a controller action named show. This happens, I get a 200 message. Now I want to update a div with the content that is being returned.
Code in controller:
respond_to do |format|
format.html # show.html.erb
format.js
end
Code in view, link and JavaScript:
<%= link_to "Show analysis", company_comparison_path(3), :remote => true , :id => "thelink" %>
<div id="replaced"> will be replaced </div>
<script>
$('#thelink').bind('ajax:complete', function() {
$('#replaced').html(data)
});
</script>
I think I still don't understand how to return the HTML or JavaScript from the controller properly into the JavaScript. If I replace the word "data" in the JavaScript with some text in brackets, I get proper output. But how do I get the result from the controller action?
You were almost there, but you need to tell the bound function what the actual html content is you want to insert into your #results div. When you call .html() on $('#replaced') the variable you use (data) is still undefined.
Try the following:
$('#thelink').bind('ajax:complete', function(event, data) {
$('#replaced').html(data.responseText);
});
edit: Oh, something to keep in mind is that this may render your view including the layout which is probably not what you want. You can add something like render layout: false if request.xhr? to your controller to prevent the layout from showing up on ajax requests.
If you want to return richer content from the AJAX response, you can render the view from the controller by the :render_to_string method.
See more: http://apidock.com/rails/ActionController/Base/render_to_string
respond_to do |format|
format.html # show.html.erb
format.js {
#content = render_to_string(:partial => 'some_partial_view')
}
end
I'm encountering a strange behavior in my controllers. They seem to occasionally want to redirect instead of render a json response.
respond_to :json, :html, :js
def create
#favorite = current_user.favorites.build(:location_id=>params[:location_id])
if #favorite.save
respond_with(#favorite)
else
respond_with(#favorite.errors)
end
end
I think it works most of the time but today I was notified of this error:
NoMethodError: undefined method `favorite_url' for #<FavoritesController:0x00000006171dc0>
The params hash was logged as:
{"format"=>"json",
"action"=>"create",
"user_id"=>"56",
"auth_token"=>"iGSty8CMIaWsbShYZEtw",
"location_id"=>"47943",
"controller"=>"favorites"}
Especially strange since it seems to work most of the time... I have changed a few of my other controllers to use the old format.json { render :json => #object } syntax but I'd like to avoid that if possible.
How could this be?
On paths that are not GETs, respond_with tries to redirect to the url for whatever it is given. You can override this with a custom Responder
