Passing parameters in rails redirect_to

How do we pass parameters in redirect_to in rails? I know we can pass id using this:

redirect_to :action => action_name,:id => 3

If I want to pass additional parameters like some form data how to achieve it?

EDIT:

For Ruby 2 syntax you have to update the snippet above to:

redirect_to action: action_name, id: 3

As a polymorphic route...

redirect_to [@mything, {key: 'value'}]

or

redirect_to [:mythings, {key: 'value'}]

etc.

As of Rails 6, you can simply call redirect_to followed by the path you wish to redirect to such as home_path, and then pass is a hash of key-value pairs.

example:

redirect_to home_path(name: 'Jason', needs: 'help with rails', help: true)

After this, you will be able to retrieve these values from the params hash.

ex

params[:name]

to retrieve the string 'Jason'

Route your path, and take the params, and return:

redirect_to controller: "client", action: "get_name", params: request.query_parameters and return

If you are looking for a way to pass additional URL parameters (not controller, action, id, etc), here's a robust method for doing so:

object_path(@object, params: request.query_parameters)

That will pass along utm parameters or any other additional params you don't want to lose.

If you are using RESTful resources you can do the following:

redirect_to action_name_resource_path(resource_object, param_1: 'value_1', param_2: 'value_2')

or
#You can also use the object_id instead of the object
redirect_to action_name_resource_path(resource_object_id, param_1: 'value_1', param_2: 'value_2')

or
#if its a collection action like index, you can omit the id as follows
redirect_to action_name_resource_path(param_1: 'value_1', param_2: 'value_2')

#An example with nested resource is as follows:
redirect_to edit_user_project_path(@user, @project, param_1: 'value_1', param_2: 'value_2')

You can pass arbitrary objects to the template with the flash parameter.

 redirect_to :back, flash: {new_solution_errors: solution.errors}

And then access them in the template via the hash.

<% flash[:new_solution_errors].each do |err| %>

Just append them to the options:

redirect_to controller: 'thing', action: 'edit', id: 3, something: 'else'

Would yield /thing/3/edit?something=else

routes.rb

 match 'controller_name/action_name' => 'controller_name#action_name', via: [:get, :post], :as => :abc

Any controller you want to redirect with parameters are given below: 

redirect_to abc_path(@abc, id: @id), :notice => "message fine"

If you have some form data for example sent to home#action, now you want to redirect them to house#act while keeping the parameters, you can do this

redirect_to act_house_path(request.parameters)
