If you're using the system Ruby, then you'll need to install gems with
`sudo`.

Most people use rvm or rbenv to avoid this (as well as enabling the
installation of multiple versions of Ruby and associated gems).

I have a problem with a form that either updates or creates depending on
whether the "project" exists already.

Im using the def create

def create
puts params.inspect
@project = current_user.projects.where(id:
params[:id]).first_or_create(project_params)
puts params.inspect
if @project.save
flash[:success] = "Project created!"
redirect_to root_url
else
flash[:success] = "Project not created!"
redirect_to root_url
end
end

Problem is it never finds the existing record.

generated SQL is


SELECT "projects".* FROM "projects" WHERE "projects"."user_id" = ? AND
"projects"."id" IS NULL ORDER BY "projects"."created_at" DESC LIMIT 1
[["user_id", 1]]
Im sending the parameters in wrong but i'm not sure of the solution.

why dont you just do this....


class Artist < ActiveRecord::Base
has_many :events, dependent: :destroy
end

class Event < ActiveRecord::Base
belongs_to :artist
end

a = Artist.first
a.events which will return a list of events connected to that artist

e = Event.first
e.artist which will return the artist that is connected to that event.

Maybe explain what your user story is to better understand. With what
you posted I comprehended the statement above.

Buenas.
Tenía una base de datos ya existente, por lo que no he tenido que
realizar migraciones.
Para decirle que tablas usa mi modelo he usado:
self.table_name = 'nombre_tabla_db'
¿Habría algo igual para hacerlo en las columnas?, he estado mirando y
no encuentro nada, todo sale con rails g migration.. y yo no quiero
realizar migraciones.

Un saludo y gracias por la ayuda.

Gemfile should in the root directory of the rails application, not in
the users home directory, which is where .gemrc should be (at least
that is where mine is). So on Ubuntu linux it is
/home/username/.gemrc

Have you debugged into the code to see what is going wrong? In particular is your filter method being called and if so what is the result?

just return true here.
i would suggest separating the conversion from the validation.

How can I refactor this coordinate validation routine so that I can use
this method with other fields of the same type, for instance, with
"full_last_position" and also maintain the cleanliness of the code and
avoiding repeating method code?

class Provider < ActiveRecord::Base
include UtilsModule
attr_accessor :full_target_area_coordinate, :full_last_position # this
field validates and saves coordinate

validate :full_target_area_coordinate, :is_valid_coordinate?

def is_valid_coordinate? # searches local geo_codes table for valid
zip
coord = self.full_target_area_coordinate.to_str
match = coord.match(/^(-?\d{1,2}\.\d{6}),\s*(-?\d{1,2}\.\d{6})$/)
if match.nil? # invalid format
errors.add(:target_area_coordinate, :invalid)
return false
end

self.target_area_coordinate =
UtilsModule.convert_coordinate(self.full_target_area_coordinate)
return true
end

end

Don't store the data like that, it will cause you endless problems and
you will look back in the future and ask why you did it that way.
Possibly it should be in separate fields, or even in a separate table.
It depends what the data represents. If you provide the context then
it may be possible to suggest the best alternative.

You have not told us which operating system you are using. Assuming
it is a linux or Mac OS then I recommend installing using rvm (others
prefer rbenv).

However I suggest that you start by working right through a good
tutorial such as railstutorial.org (which is free to use online).
This tutorial runs in the cloud and does not need you to install
anything to get going. Once you have learnt the basics then
installing on your own machine will be easier as you will know what to
expect.

As a matter of interest why have you installed an almost obsolete
version of Rails? 4.2.4 is the current version.
