Error with Geocode, Rails and Mongoid

Question

I'm using Rails 3.2.16, mongoid and geocode.

I've set up the model for my profile to convert the street and city address into long/lat. This is working well. I also have a search that's based on geocode - which also works. It searches for profiles with in certain distances etc.

Even when I misspell a city in the search it's intelligent enough to figure out what I actually mean.

However, when I search for something that really stumps geocode, like "sgervwsewerw", it throws the "We're sorry, but something went wrong" error. How can I prevent this error and just have it send back no results? Here is the error information:

See https://github.com/mongodb/mongo/blob/master/docs/errors.md
for details about this error.):

Here is the code from my profile controller:

def index
 if params[:profile_search].present?
    @profiles = Profile.near(params[:profile_search], 25, :order => :distance).desc("position_order")
  else
    @profiles = Profile.desc("position_order")
  end
end

Answer 1

Your problem seems to be in the NaN argument in the $nearSphere for coordinates. Make sure, you provide correct values for the comparison (eg if using the users location, make sure it is available).

Hope that helps.

Answer 2

In your mongoid.yml initializer file you will find a line like:

# Raise an error when performing a #find and the document is not found.
# (default: true)
raise_not_found_error: false

default it's true, if you set it to false you will not get this error anymore.
