Re: [Rails] http requests

Ruby on Rails Wednesday, May 31, 2017

Hassan is correctly encouraging you towards the higher-level abstractions, like a Gem specifically written for this purpose.


If you really want to know how to make outgoing http requests, the answer is the Net::HTTP Ruby library, which is documented here:


But as Hassan said if there's a higher level abstraction, like a Gem, prefer that to writing your own low-level code.

But as a ruby developer the Net::HTTP Ruby library is at the very least something you should learn about and play around with, even if you don't actually need it for this immediate purpose.

Searching for `ruby gem canada post` turns up more than one -- why
don't you just try them and see which you prefer?

Similarly `ruby gem http` will show you some possibilities if you want
to roll your own solution. See also:

You can certainly do that, if one of the gems doesn't meet your needs.

Have you read the Canada Post API docs?

[Rails] http requests

Ruby on Rails

Hmm, which gem would allow you to perform http requests within Rails?  I would like to send a request to the canadapost website and pass it some parameters and return a shipping total.

I do believe there is a canadapost gem, but I'm not sure how upto date it is.

I guess the other option is to like add paramters to a url and open that page on a new tab?

Thanks,
Joe

Re: [Rails] rails 4.2 query with operator in

Ruby on Rails

I suspect the issue is that you've referred directly to a primary key called `projects.id` in your SQL, but (from the `belongs_to` call) we can see that column is actually called `baseline_id`.

Have you tried changing 'projects.id IN (?)' to 'projects.baseline_id IN (?)' in your initial query? That might sort it.

Re: [Rails] rails 4.2 query with operator in

Ruby on Rails

First of all, thank you for your quick reply!!!

The relation is a bit complex:

in the investment's model there is this relation:

belongs_to :project, :class_name => "Baseline", :foreign_key => :baseline_id
this is the relation between investment and project

Em quarta-feira, 31 de maio de 2017 11:47:19 UTC+1, Marco Antonio Almeida escreveu:
Hi João,

The problem is that you don't have a field called 'projects.id' in the 'investments' table. Does your investment model belongs to one project? Then you would do 

Investment.revenues
  .where(project_id: @projects.map { |p| p.id })
  .includes(:expenses, baseline: [:project, :coordinator])

However, I need to have more information on the database schema to have a better insight. It could also be that you have a many to many relationship between projects and investments and you would need other setup for that, but it depends on how the fields are setup.

Kind regards,

Re: [Rails] collection_select

What is the relationship between a club and a press release? Does a club have many press releases? Start with the real-world relationship, then add that relationship to your Rails models. The answer will suggest itself.

I have configured database.yml and tnsnames.ora correctly but not sure why I am getting this error . Is Oracle 10 is the reason for this error ? Please suggest . FYI , I am able to connect and fetch result of SQL queries manually through the terminal using below command ;


ruby -r oci8 -e "OCI8.new('user',  'password', '//databasehost:1521/testdb').exec('SELECT * FROM application_account') do |r| puts r.join(' | '); end"


But not sure why it's creating problem at rails app level . I tried all the solutions that I found on google but none of them worked .

Re: [Rails] notifications

Ruby on Rails Monday, May 29, 2017

ok, the context is I have this table to update users with small notifications messages. 

Rails scaffold generated a userid and msg form.   Now, when I need to send a user a message I look them up in the table, grab their id and then put the id in the field along with a message.

Thanks,
Joe

When (how often) would you want to get the user's name? That's the question I would ask before deciding whether to denormalize this or not.

If you're just doing a listing on a table, you could do Notification.includes(:user).where ... and that would lazy-load the users for you, so you could get the user's name without an N+1 lookup. If you are showing the user all of their notifications, then you would be doing something like current_user.notifications ... so you would have the user already that way.

The answer to your question depends on the context.

[Rails] notifications

Ruby on Rails

Hi, I have this notifications table which basically has a userid and a msg (notification).

What should I do with the userid?  I would like to look up the user by name and stick the id in the table.  

Is that normally what you'd do in this case?  A dropdown list would be too large.

Thanks,
Joe

No, form_tag creates a form tag, unbound to any model object.

http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html#method-i-form_tag

I think where the OP may be getting off track is that the form created by form_tag doesn't have a bound object, so saying f.collection_select is sort of meaningless. That syntax is used when you bind the form to an object, such as when you use form_for(@foo). You can use collection_select with or without an object, in the latter form, you have to provide the object as the first argument, but when you use the f.collection_select syntax, that first argument becomes the second argument, and the first argument is picked up from the f reference.

I think, ultimately, that's what's going on here -- the entire set of arguments to the helper are being shifted left one step, and the meaningless reference to the form builder (without bound object) is being passed in to the tag helper.

[Rails] Nested Form find or create inside of form

Ruby on Rails

Good morning,


I haven't done an autocomplete with a nested form in quite some time and can't find any good references.  I posted to SO here: https://stackoverflow.com/questions/44232005/rails-5-nested-form-find-or-create

Basically I have two models Run and Patient.  Run belongs_to patient and Patient has_many runs.  Run accepts_nested_attributes for patient.

What I want to do is when creating a new run, have a select box that let's me type out of the name of the patient, if they exist and it's the right patient, use that ID in the form.  If the patient does not exist, then create the nested association patient record.  I'm hoping to do this with autocomplete too.

Any guidance is greatly appreciated.

Thanks!

form_tag must be used inside a form, it does not create a form

"works" in the sense that you have tests for this part of your code?

That aside, having a "requests" controller sounds like a phenomenally
bad idea -- "request" and "response" have very specific meanings in
any web application, and in the case of Rails request() is an instance
method of ActionController::Base.

I would strongly recommend changing the name of that controller :-)
