About action create

Rails
1

there i hava a model named Person
the controller is People
in the new.html.erb file function form_for(@person) make the start
form tag #@person=Person.new

i think it’ll call “create” action in PeopleController when invoke
submit button
but not!
it just renders index.html.erb and never access to action create

sorry to my poor English :smiley:
wish i hava descriped it clearly…

Your
@person = Person.new
should be in the people_controller…

I’d say start with a new rails project…

Generate a scaffold for your person model

→ ruby script/generate scaffold person last_name:string
first_name:string dob:datetime

look at the source that is written for you, i.e., new.html.erb has

→ <% form_for(@person) do |f| %>
→ … field stuff…
→ <%= f.submit “Create” %>
→ <% end %>

setup your database, and all that… then browse to
http://localhost:3000/people - click the “New person” link, and look
at the page source if you’re curious

add a person, fill out the fields and submit. That should hit your
people_controller create method (it’s a POST, after all).

While not necessarily how you’ll end up writing your app in the future,
the scaffolded code is a great resource to read in the beginning to see
how Rails fits it all together.

thx ! here is my source code .
PeopleController
def new
@person=Person.new
end
def create
@person = Person.new(params[:person])

respond_to do |format|
  if @person.save
    flash[:notice] = 'Product was successfully created.'
    format.html
    format.xml  { render :xml => @person, :status

=> :created, :location => @product }
else
flash[:notice]=“dont saved”
format.html { render :action => “new” }
format.xml { render :xml => @person.errors, :status
=> :unprocessable_entity }
end
end
end

new.html.erb
<% form_for(@person) do |f| %>
<%=f.text_field :first_name %>
…
<%end%>

something wrong here ?

i guess there is something wrong with ROUTER

first i insert data items to mysql database via PHPMYADMIN,
the INDEX method show out them
but when i click the “show,edit,destroy"links
rails give me the response “No action responded to 1” the number is
person id.
anyone can tell my why?

Yes!just the ROUTER.rb!
here is the code
map.resources :people

Install the default routes as the lowest priority.

map.connect ‘:controller/:action/:id’
map.connect ‘:controller/:action/:id.:format’
at the beginning i put “map.resources :people” on the end .
i think this cause something wrong
