I''d like to create multiple records at once, but I''m having
trouble with
text_field helper tag.
if i have the following within a form:
<%= text_field ''contact'', ''name''
%><%= text_field ''contact'', ''number''
%>
<%= text_field ''contact'', ''name''
%><%= text_field ''contact'', ''number''
%>
I would like to somehow get an array of contacts in my params like:
contact => [ {name => "foo", number => "1234"},
{name => "bar", number =>
"9876} ]
is there anyway with the naming convention to get this to work with the
text_field tag? or at the least a regular input tag?
I tried the following, but it didn''t work:
<%= text_field ''contact[1]'', ''name''
%><%= text_field ''contact[1]'',
''number''
%>
<%= text_field ''contact[2]'', ''name''
%><%= text_field ''contact[2]'',
''number''
%>
I recieved the following error:
`@contact[1]'' is not allowed as an instance variable name

It doesn''t work for me. If I do it like:
<%= text_field ''contact'', ''name''
%><%= text_field ''contact'', ''number''
%>
<%= text_field ''contact'', ''name''
%><%= text_field ''contact'', ''number''
%>
I get the following in my parameters:
Parameters: {"commit"=>"Create",
"action"=>"create",
"controller"=>"my_controller", "
contact"=>{"name"=>"name1",
"number"=>"1111"}}
there is only one "contact", not an array of contacts as you say.
As a workaround, I''m doing:
<%= text_field ''contact_1'', ''name''
%><%= text_field ''contact_1'', ''number''
%>
<%= text_field ''contact_2'', ''name''
%><%= text_field ''contact_2'', ''number''
%>
but I''d rather not have to name them like that, and have an array of
"contact" or at least two different arrays as you stated of
"name" and
"number" within a "contact" param

my question was about creating multiple new records, not updating existing ones.

Hi! Can''t you create a temporary @contact instance variable as an array of contacts and in the form do: <%= text_field ''contact[]'', ''name'' %><%= text_field ''contact[]'', ''number'' %> <%= text_field ''contact[]'', ''name'' %><%= text_field ''contact[]'', ''number'' %> /Jonas deanholdren wrote:> I''d like to create multiple records at once, but I''m having trouble with > text_field helper tag. > if i have the following within a form: > > <%= text_field ''contact'', ''name'' %><%= text_field ''contact'', ''number'' %> > <%= text_field ''contact'', ''name'' %><%= text_field ''contact'', ''number'' %> > > I would like to somehow get an array of contacts in my params like: > > contact => [ {name => "foo", number => "1234"}, {name => "bar", number > => > "9876} ] > > is there anyway with the naming convention to get this to work with the > text_field tag? or at the least a regular input tag? > I tried the following, but it didn''t work: > > <%= text_field ''contact[1]'', ''name'' %><%= text_field ''contact[1]'', > ''number'' > %> > <%= text_field ''contact[2]'', ''name'' %><%= text_field ''contact[2]'', > ''number'' > %> > > I recieved the following error: > > `@contact[1]'' is not allowed as an instance variable name-- Posted via http://www.ruby-forum.com/.
Dean Holdren wrote:> my question was about creating multiple new records, not updating > existing ones.You sad you "would like to somehow get an array of contacts in my params". And thats the way to do it: call the fields in your form like this: <%= hidden_field_tag "movie[id][]", movie.id %> <%= text_field_tag "movie[title][]", movie.title %> <%= text_field_tag "movie[description][]", movie.description %> <%= hidden_field_tag "movie[id][]", movie.id %> <%= text_field_tag "movie[title][]", movie.title %> <%= text_field_tag "movie[description][]", movie.description %> <%= hidden_field_tag "movie[id][]", movie.id %> <%= text_field_tag "movie[title][]", movie.title %> <%= text_field_tag "movie[description][]", movie.description %> and you will get an array in your controller that you can access. ps. please quote my message correctly next time
Can we get an example of this? With the controllers and views required to do this?
