undefined method `to_gmaps4rails'

[HungYuHei]

I've done everything that the README said

but I still got "undefined method `to_gmaps4rails' for #User:0x007f9ea726af78" error

btw, my environment is : rails3.1, mongoid2.3.3, gmaps4rails1.4.2

and here is my Model snippet:

class User
  include Mongoid::Document

  acts_as_gmappable
  field :name
end

my controller:

...
@json = @user.to_gmaps4rails
...

Did I miss something ?

[HungYuHei]

a moment ago, I changed something(but I forgot the details), then I got "undefined method `gmaps4rails_options'"

please notice that the piror error I mentioned is "undefined method `to_gmaps4rails'" which is different

I have made a pull request for this If you are just developing you can use my repo branch is "MoveIn.."

[apneadiving]

just released 1.4.3 let me know if you still have this problem

[HungYuHei]

Due to this issue, right now I manually call the google-map API instead of using the gem

However, I would like to do some test later :)

I have a same issue over here. My environment is :

1. Rails 3.2.1
2. Mongoid 2.4.3
3. gmaps4rails 1.4.5

[apneadiving]

@zolzaya : ok I think I understand.

In Mongoid: User.all is a Mongoid::Criteria. I should add to_gmaps4rails to this class.

In the meantime, you can simply do: User.all.to_a.to_gmaps4rails

[zolzaya]

Thank you for reply. It's working fine. :)

Apnea, I have encountered this problem many a time: undefined method gmaps4rails_options. The only way I can bypass it is by doing .to_json instead. However, that is in the case of polylines, polygons, etc etc. But when it comes to markers, even if I do .to_json, I just get a grey map :(

This is incredibly frustrating. Any ideas?

Rails 3.2.3 ruby 1.9.3p0

Edit: I just did bundle update and now it's gmaps4rails 1.4.8 (still same error). Certain version I should try? I'll try 1.4.3.

@DavidPardy : what orm do you use?

[ornerymoose]

I'm new to web dev but I'm fairly certain the ORM would be Active Record?

Also here's a github to what I'm trying to accomplish. Fairly simple: create a location in /locations, create a map in /maps using the location_id, and boom the location shows up on the map as a placemark.

https://github.com/DavidPardy/Placemarks-Using-Gmaps4Rails

Edit: The map controller and map view is a little messy, just because I'm toying with stuff. Also, I have tried 1.4.3, 1.4.7, and 1.4.8, not working for any.

[apneadiving]

Well you do Map.all.to_gmaps4rails but Map doesn't contain acts_as_gmappable

[ornerymoose]

Right, good call, not sure how I missed that. n00b like I said.

I amaze myself sometimes. I just started a new app with just a map model and that's much easier.

Thanks alot for your help sir, greatly appreciate it.

[apneadiving]

@DavidPardy No problem, we all face this kind of situation. Have fun coding :)

[ornerymoose]

Don't hate me if I come back with more questions later, lol :)
