Rails 3 google maps

问题

I'm trying to create a sample project with gmaps4rails gem: But getting an error:

undefined method `gmaps’ for #
Rails.root: /var/www/brandbk
Application Trace | Framework Trace | Full Trace
app/controllers/locations_controller.rb:46:in `block in create’
app/controllers/locations_controller.rb:45:in `create’
Request
Parameters:
{“utf8″=>”вњ“”,
“authenticity_token”=>”CSpi+VhUe8CtF+4R6zxMEXbB8ofa0QxUF1ntGl+N1Ss=”,
“location”=>{“address”=>”rwr”},
“commit”=>”Create Location”}

Like this: http://pastebin.com/zGP9Z7vE Can anyone help me please?

My models and controllers are valid and same as described on the project wiki. Thanks.

回答1:

It comes from here:

return true if gmaps4rails_options[:check_process] == true && self.send(gmaps4rails_options[:checker]) == true

Basically this line prevents geocoding if:

• it's not requested
• or if it's requested but not already done

So two ways to get rid of it:

• set the check_process to false
• add a boolean column to your model named gmaps (this could be done with a method as well)
