Swapping key names in a hash

[clem_c_rock]

Hello,

I'm trying to change the name of a hash key. I want to take a params[:value] and modify some of it's key names to work better in model sql statements.

for instance I have a param hash key named "title" (params['title']) and I want to change that key name to 'spaces.title' so it will work better w/in a conditional statement in joined table sql call.

Any ideas?

I'm not even sure you can alter the params hash. I've never tried it personally.

In any case, I'd just create a new hash with the key names you want, then pass that to whatever SQL-creating method you need.

Don't do this ;-).

Could you describe your query, params hash and database tables. I'm sure there is a Rails-way to handle this.

Hello,

I'm trying to get the column names associated w/ this record set:


account_all = Account.findall)


Since account_all is an array - how do I get the names?


I know there's got to be a simple way to do this.

Of course there is!

Account.columns  # returns all columns
Account.content_columns  # returns all columns you want to show to your user (excludes id, xxx_id, xxx_count columns)

This will display all columns along with the values in the @account object:

<dl>
<&#37; for column in Account.content_columns %>
<dt><%= column.human_name %></dt>
<dd><%= @account.send(column) %></dd>
<% end %>
</dl>

I'm not 100% sure that @account.send(column) works though.

Sweet - here's what I was looking for:

account_all.first.attributes.keys

If you want *that* you can use Account.column_names.
