Hi, I am new in RoR and i am lost in a simple action. In my home page i am trying to call a create action from a different controller. Here is how i do it:
<%= link_to "Join!", :controller => "participants",:action => "create",:user_id => 2,:defi_id => item.id%>
What am i doing wrong? It should be a post action, how do i specify that?
Thank you for your help Greg
Do you want to create a Participant?
I think you should use POST when you want to create a record in database. Normal a link always a GET request, so maybe you could
create a form or use <%= link_to “Join!”, participants_path, :method => :post %>, you could check the api for details

I think i should try this as i want to insert a new participant
<%= link_to "Participer!", new_participant_path, :method => :post %>
But this only redirects me to the page, how do i add the parameters to actually insert data?
When you click “Join!”, you want to create a participant and then redirect to somewhere, is that right? If so, you should post your data to the controller, by using <%= link_to “Participer!”, participants_path, :method => :post, :group_id => @group.id %>. when you click the link, the ‘create’ method in the according controller will be executed.
or you could create a form yourself, just put your parameters in the hidden input, as:

<form action="/participants">
<input type="hidden" name="paramter" value="value" />
<input type="submit" name="submit" value="Join"/>
</form>
Yes i know i could use a form but i prefer to use a link_to. Is it better use a from instead?
I did this: <%= link_to "Participer!", new_participant_path, :method => :post,:defi_id => item.id,:user_id => 2 %>
but it still doesn't create the data into de db, it redirects me to the new template.

i think it should be <%= link_to “Participer!”, participants_path, :method =>:post, :defi_id => item.id, :user_id => 2 %>
not
<%= link_to “Participer!”, new_participant_path, :method =>:post, :defi_id => item.id, :user_id => 2 %>

Thanks we are on the good track. But there is a last problem, the parameters arent posted. I've checked with firebug.
so how about using button_to?
I think this could be useful for you

I've replaced link_to by button_to and it does the same thing. Do i HAVE TO use a form_for?
What parameters aren't posted? If you want additional parameters in the link you will need to include them in the link_to. Have a look at the generated html for the link to check that what you want is there.
Where is the data coming from? If it is user input why not use a form with a submit button?

What do you see in the log file when you click the link? It should show the params.
