Hi to all,

i’m trying to pass the id of my record within the multipart form.  
I’ve tried to pass it like this but it gives a compile error…

\<%= form\_tag( { :action =\> ‘create’, :id =\> @nominee }, :multipart =\>  
true ) do -%\>  
\<%= render :partial =\> ‘form’ %\>  
\<%= submit\_tag ‘Edit’ %\>  
\<% end %\>

\<%= link\_to ‘Show’, :action =\> ‘show’, :id =\> @nominee %\> |  
\<%= link\_to ‘Back’, :action =\> ‘list’ %\>

Can anybody help me???

Thanks i advance

Andrea

You typically won’t pass an id to a create action. I’m doing this  
with an update action using the same syntax that you have, and it  
works fine. If it matters, I don’t have an equal sign next to my  
form\_tag (i.e., \<% form\_tag…, not \<%= form\_tag…).

Do you want to set the id of the record that you’re creating (not  
recommended), or are you trying to pass a value to the record like  
nominee\_id = 12?

If you’re still having problems, please paste the error.

You’ll need

\<%= form\_tag( { :action =\> ‘update’, :id =\> @nominee }, {:multipart =\>  
true} ) do -%\>

While Ruby will attempt to do “THE RIGHT THING”, you’ll find that if  
you specify the hash curly-braces on the first hash, you’ll also need  
to specify them on the second hash.

Hi Julian,

i still have an error, the code is:

# Editing nominee

\<%= form\_tag( { :action =\> ‘update’, :id =\> @nominee }, {:multipart =\>  
true} do) -%\>  
\<%= render :partial =\> ‘form’ %\>  
\<%= submit\_tag ‘Edit’ %\>  
\<% end %\>

and the compile error:

compile error  
script/…/config/…/app/views/nominees/edit.rhtml:4: syntax error,  
unexpected kDO, expecting ‘)’  
\_erbout.concat(( form\_tag( { :action =\> ‘update’, :id =\> @nominee },  
{:multipart =\> true} do) ).to\_s)  
^  
script/…/config/…/app/views/nominees/edit.rhtml:5: syntax error,  
unexpected tIDENTIFIER, expecting ‘)’  
\_erbout.concat " "; \_erbout.concat(( render :partial =\> ‘form’ ).to\_s);  
\_erbout.concat “\n”  
^  
script/…/config/…/app/views/nominees/edit.rhtml:12: syntax error,  
unexpected kEND, expecting $end

what could it be?

do has to come after the close parenthesis… do reprsents the start  
of a block, and comes after the other arguments, which go inside the  
parenthesis.

\<%= form\_tag( { :action =\> ‘update’, :id =\> @nominee }, {:multipart =\>  
true}) do -%\>  
\<%= render :partial =\> ‘form’ %\>  
\<%= submit\_tag ‘Edit’ %\>

\<%= render :partial =\> ‘form’ %\>  
\<%= submit\_tag ‘Edit’ %\>

You shouldn’t use \<%= %\> when you’re using the block form.
