def resolve_create
@resolve = Resolve.new(params[:resolve1])
if @resolve.save
redirect_to :action => ‘list’
else
redirect_to :action => ‘resolve’

Otherwise u can try this one

def resolve_create
@resolve = Resolve.new()
@resolve.content = params[:resolve][:content]
if @resolve.save
redirect_to :action => ‘list’
else
render :action => ‘resolve’
end
end

Thanks

def resolve_create
@resolve = Resolve.new(params[:resolve1])
if @resolve.save
redirect_to :action => ‘list’
else
redirect_to :action => ‘resolve’
end
end
Problem is in parameters arguments…

It should be params[:resolve] …not params[:resolve1]…

Thanks

one -many…

Hi Ralu rm

i have an error
undefined method `stringify_keys!’ for “”:String

The reason for this error is in the line

<%= form_tag :action => ‘resolve_create’, :resolve => @resolve %>

Since this will generate source like
action="/controller/resolve_create?resolve="

And in resolve_create what you are trying is

@resolve = Resolve.new(params[:resolve])
if @resolve.save

Here the error is .Why are you passing :resolve => @resolve ?

<%= form_tag :action => ‘resolve_create’, :resolve => @resolve %>

resolution:
<%= text_area 'resolve','content', :cols => 40, :rows => 12 %>

<%= submit_tag “save” %>

Try below code

<%= form_tag :action => ‘resolve_create’ do %>

resolution:
<%= text_area 'resolve','content', :cols => 40, :rows => 12 %>

<%= submit_tag "save" %> <%end>

ralu · October 22, 2009, 12:15pm

Hi Ralu rm

That is already there in params[:resolve]

Sorry to butt in guys, i get the feeling you’re going to go round in
circles forever.

Ralu - if the user types ‘foo’ in the text box, params will look like
this:

params = {:resolve => {:content => “foo”}}

In the controller you need to do this:

@resolve = Resolve.new(params[:resolve])

which is the same as saying this

@resolve = Resolve.new({:content => “foo”})

which in turn, effectively does this

@resolve = Resolve.new
@resolve.content = “foo”

Do you see?

Like Sijo says, you don’t need :resolve => @resolve in the form - this
is going to break the form by overriding :resolve in your params,
effectively deleting the parameter from the text field. It would be
better if you sticked to the standard restful scheme and your form
looked like this:

<% form_for @resolve do |f| %>

resolution:
<%= f.text_area 'resolve','content', :cols => 40, :rows => 12 %>

<% end %>

This will submit to the ResolveController.create action, which is where
you should create a resolve object/

ralu · October 22, 2009, 12:42pm

Oops, sorry, that text area in the amended form should be

<%= f.text_area :content, :cols => 40, :rows => 12 %>

I know you’re a beginner, but if you know the name of the method that
you have a question about, your first stop should always be the api.
