Re: [Rails] Re: ROR + React

[Noel]

There are at least 4 different ways that I'm familiar with and tons of 
resources to help you execute the way that works best for you. Here's the 
ones I've learned from researching:

1. Approach 1 - CDN based inclusion in header

- You can include it just as a link on the html pages you want to include 
some React functionality. This is as simple as putting it in the header of 
the pages. 

2. Approach 2 - React Front-end/Rails API backend (pre-existing app)

- Convert controllers into API folders with namespacing technique and 
create the front-end `client` as shown in Approach 3.

3. Approach 3 - React Front-end/Rails API backend 

- This approach works by creating a rails api 
rails new myapp --api

- Within the directory of the app run
create-react-app client

- Install foreman gem, create Procfile with the following:
RAILS: bundle exec rails s -p 3001
REACT: cd client && npm start
* (caveat: If deployed on Heroku, **you may need to change `REACT` to 
`web`.)*

- Run servers by
foreman start

- You will need something like axios in node to make the front-end `client` 
talk to the rails backend but this works. 

4. Approach 4 -React-rails gem install
- This approach, I cannot speak to because it seemed the most  coupled. 
In the back of my mind, I tend to think this couples react to rails in a 
way I, at this level of my knowledge, would not be able to decouple if I 
were to revert to something else or use Vue or stick to normal html 
requests. 

Forgive me giving my opinion on that last one, if someone has more insight 
on the gem approach, I'd be happy to hear it.

Re: [Rails] Basics: How does Javascript communicate with Ruby on Rails?

[Noel]

Hey Jason,
Thank you for the book recommendation, a good addition to what I have 
so far with books on Rails and Ruby. I have gone through many of the 
sections of the Rails guide and the edge version. The drill down that 
approach that Walter described is something I'm doing, but now I'm just 
trying to find the point of origin with each gem/module. So much magic, 
hard to tell when you hit paydirt. As for Ruby itself, I've explored it 
regularly for a while now, just feel like it sticks when I need to use the 
information. Thank you again for the recommendations, much obliged.

Re: [Rails] Basics: How does Javascript communicate with Ruby on Rails?

[Noel]

You just hit everything that I was trying to figure out and then some. This is 
what I’ve been needing to know(I can’t be certain of the that). Last question, 
how did you figure that out?; because that’s where this is kind of 
embarrassing, that I’ve held out to ask this for so long for fear. I’m sure 
intuition and experience comes with understanding what’s under the hood, but 
how does a junior dev figure stuff out like this? Please be merciful, don’t say 
look at the documentation, the documentation needs documentation. The 
documentation is not very clear for a junior dev because some stuff is 
abstracted and it’s like you have to be in the know about some other 
concept(that is omitted because reasons) that isn’t mentioned but understood.

Goes without saying but thanks man, this is solid knowledge I can use.

Re: [Rails] Basics: How does Javascript communicate with Ruby on Rails?

[Noel]

Genuinely, I thank both of you for your insights. Without stretching this 
thread out any more, I want to figure out one last concept. 

Form data, based on what was mentioned above, is it that the headers dictate 
what is passed on as data to be persisted? Like where in the chain of events 
does the SQL know that this is the data to be persisted? I think that’s where I 
get foggy, I understand the concepts of the http request/response but at what 
point is the data from a form understood or decided or interpreted by SQL? 
That’s all in the adapter?

[Rails] Basics: How does Javascript communicate with Ruby on Rails?

[Noel]

Hello to All,
 I'm trying to understand something that I seem to get lost on, which 
is how exactly does Javascript communicate with Rails? I understand how to 
make it work, I can even make a React front-end and Rails API work 
together. But I feel like I am missing something fundamental when it comes 
to how this communication actually occurs. If you know if a resource that 
explains this, I would be grateful.

Also, how does SQL communicate with Ruby or viceversa? A good resource that 
breaks it down would be great.

[Rails] redirect_to flash

[Rails] Charset encoding issue

[Noel]

I am working with an SQL Server database on a windows server with collation
SQL_Latin1_General_CP1_CI_AS

When I go to the rails console on the Linux server with the app I get
= Rodríguez, César

To try to isolate the problem in my controller I tried render :text =

but on the browser I am seeing

Rodr?guez, C?sar

I believe this is an encoding issue, but I don't know how to
resolve.(and Google + Stackoverflow are failing me)  Given that the
source data can't be changed, what do I need to do on the rails side
to get the text to render properly?

On Chrome I have tried to manually change the encoding and no matter
which I select I can't get the text to render correctly.

Also, why would it render correctly on the console?

Thanks,
Noel

 I believe those two are just the most common.

 Look at the rest of the code, though. It looks like you can specify other
 flash values like so:

 redirect_to suppliers_path, :flash = { :success = 'Supplier was
 successfully created.' }


Thanks Tim, I didn't get that from the code.

When I used redirect_to I was expecting
   redirect_to suppliers_path, :whatever
would produce flash[:whatever]

At least this is a good workaround for me.

Re: [Rails] Gemfile.local along with Gemfile?

[Noel]

 Hi all!

 I'm wondering if there is any elegant way to have some gems locally in
 a rails 3.2 + ruby 1.9 project but not have them in the Gemfile and
 therefore not in source control.

 The reason is very similar to this:

 http://stackoverflow.com/questions/3752906/how-to-use-a-gem-in-rails-3-without-referencing-it-in-the-gemfile

 I work on a large team and we moved to Ruby 1.9.3 but ruby-debug19
 doesn't work with 1.9.3 unless you do some weird stuff. I got it to
 work, but it totally taints the Gemfile (references RVM paths). Plus,
 some people on the team don't use or want to use ruby-debug. It occurs
 to me that this is probably a bigger problem than my issue.

 Specifically: with bundler, is there some way to have project gems AND
 local gems, where the local gems aren't part of the project?

 In my case, I'd then be able to have ruby-debug hacked and configured
 for my local development, but it wouldn't be in the Gemfile and thus
 wouldn't mess up the other devs.

 Thoughts?


What about defining a constant in an initializer that is not checked
in then do something like what is shown in the bundler section here:

https://github.com/bbatsov/rails-style-guide

 To make mysql the default when you run rails new you would have to modify the

 scratch myself, but I can certainly use it and modify it to handle the
 naming conventions in my existing schema.  Now I have to go back to working
 on updating Dr. Nic's magic_model_generator to work with rails 3.

 Bertly, you might want to take a look at Geocoder:

Re: [Rails] simple form question

[Noel]

it sounds like users can only create sites to their own customer
records.  This is authorization and can do handled with something like
the cancan gem.



On Thu, Jul 7, 2011 at 5:36 AM, paulo paul.a.taylo...@gmail.com wrote:
 Hi folks,

 I've done this a few ways that have all seemed a bit 'nobby' so was
 just wondering if there is a recommended way to achieve the following:

 I have 2 models, 'customers' and 'sites' which are connected with a
 has_many/belongs_to relationship.
 I have the scaffold form which creates customers, which is as desired,
 but I ONLY want to be able to create a site after going through
 the :show page of a customer and selecting an 'Add new Site' link.

 To do this, I can obviously just provide a link_to to the sites/new
 controller, but I need to pre-populate the sites 'customer_id' field,
 without displaying this in a way that could be manipulated (e.g. in
 the URL as a parameter).

 Unfortunately, I do need the 'sites' form to be on a separate page to
 the customer show page, otherwise it would have been very easy.


 Is there a better solution that POSTing to the site form with the
 values from the :show page, to then POST to the create method?


 Really appreciate any pointers on this,

 Paul

On Jun 2, 2011, at 3:53 AM, Sta Canovist stacanov...@gmail.com wrote:

 Yes, Im new to Ruby. COming from PHP/Java world. I DON'T want to learn
 ruby, sigh.
 Anyway I got a project that is done in ruby and it need some
 modifications sometimes.
 
 So until now, dont know how, I managed fixing a few things on that
 application.
 Sometimes was about setting a page to show more fields than before. Or
 maybe block a page redirecting it to an access denied page.
 
 But now things are gotting more serious and bigger modifications are
 needed. I think I can manage doing that. But working like have done
 until now is VERY unefficient. Basically, Im working directly on a
 test server. I NEVER managed (this is the real big problem) in
 installing the app, correctly, on my local machine. Im getting mad in
 trying to do it it but with no success.
 
 Thus the problem is about succesing in making the local app working.
 Explaining in details everything I guess would make most of you stop
 reading this post. So I try with another strategy. Here it comes:
 
 I am on MAC. Ruby is installed by default. I MUST use Apache as
 server. So I put a virtual host poiting to /MY_PATH_RO_ROR_APP/public
 
 When typing http://localhost/ then I see the content of the public
 folder.
 
 The APP is empty. Im not using things like generate or scaffolding.
 Why? Well, because my thought was to just copy all the application
 located on the test-server and making it work. Is that bad? I dont
 know. I would prefer not to go through all ruby stuff.
 If it is bad it is ok, as long as this is not the cause of the thing
 that the app is not working.
 
 What I need to do is to create a controller manually and connect it
 through the route.rb.
 
 i create a file in the app folder named product_controller.rb:
 
 class ProductController  ApplicationController
 
  def show
render :text = 'abcd'
return
  end
 
 end
 
 
 Now I want to map the route. How can I do this? I tried different
 ways. For example:
 
 map.resources :product
 
 or
 map.connect ':controller/:action/:id'
 
 or
 map.connect ':controller/:action/:id.:format'
 
 or
 map.connect ':product/:show'
 
 Well, everytime I try then to type something in the browser. I try for
 example:
 
 localhost/product/1
 localhost/product/show
 localhost/product/1/show
 localhost/product
 
 Well, all the time I can see the same error in the log:
 
 File doesnt exist.
 
 Right now Im thinking that the url-requests are managed by apache. And
 that apache doesnt understand that this is a ROR app? Is that the
 problem maybe??? And does anyone know how to make apache understand
 that that one is a ruby app??
 

Apache alone can't serve a Rails app. You need passenger. 

Rails also comes with a webserver if u cd to the project dir and type 
script/server

If you need to maintain a rails app it might be good to learn some Ruby. Trust 
me there are worst things out there. Google tryruby

Above I made the guess that ur  app is not rails 3. You should find what 
version of rails you are using because something like routing differs.

Re: [Rails] Rails 3.1.0.rc1 assets not compiling

[Noel]

found the problem.

There can't be any blank lines in the manifest

https://github.com/noel/happy/blob/master/app/assets/javascripts/application.js#L8-10

Is this a bug or should the text in the generated file be more explicit?

 I set up 2 .coffee files with alerts and expected //=require_tree to

 ran rake assets:precompile and indeed the file in public/assets
 matches what I see in the browser.

 Here is a list of my gems

 and here is my sample app

 I also tried requiring specific files like
 //= require foo
 and that had no effect.

 interestingly if I also required a file that does not exist like
 //= require bar

 I see no console errors during compilation

 Any ideas what could be the cause?

[Rails] Re: Wrong information

[Noel F.]

Hi Peter,

Thanks for the help, so is it a problem in the browser or problem with 
ruby?
I can manually type 105°C and it works fine.

Regards,
Noel

[Rails] div_for and RJS

[Noel Miller]

Do you have to use an activeRecord object for div_for?
Perhaps I'm taking the wrong approach for dynamic divs

so far my education:

1. id= , is fine for just one div and prototype activity in an RJS (I
got this to work)
2. class= , another option, but I don't see how it can be used
3. div_for , a helper that uses ActiveRecord objects to come up with
multiple divs

Below: code that is my best guess for how to proceed, but it doesn't do
everything it is supposed to do:


script src='http://pastie.org/472556.js'/script

script src='http://pastie.org/472563.js'/script

[Rails] calling save in after_create hook

[Noel Walters]

Scenario:

I'm creating an image file upload service for my web site.

As well as saving the actual file I also need to create a database
record for the file.

I would like to name the file after the record id, but I also need to
save some attributes of the image (width/height/mime_type etc) which I
can't discover until after the file is created.

The Problem:
1) The id is not available until after the record is saved so I can't
create the file until after the record has been created

2) if I try to update the record in the after_create hook it creates an
extra record in the database instead of updating the existing one.

Is this a bug?

Any advice to resolve this problem would be most welcome.

It could be done in the controller of course, but I feel it belongs in
the model.

OK - my bad. All works OK, can't explain how I made this mistake but it 
seems it was working all along.

[Rails] send_file problem with IE7. Save Image as untitled.bmp

[Noel Walters]

Platform = Linux and Mongrel

I'm using send_file to send images from a controller. like this:

send_file( @content.location, :disposition = 'inline', :type =
File.mime_type?(@content.location)) # mime_type? courtesy of mimetype_fu

This is called for in an ordinary img tag.

It all works perfectly except for one minor hitch which is driving me
mad.

If you right click on the image in IE7 and choose Save Image As... the
file save dialog always defaults the filename to untitled.bmp.

Other browsers always get the correct file name (usually something like
61.png or 18.jpg)

If I copy the file into the corresponding path under RAILS_ROOT/public
then IE7 will get the filename correct - as will all browsers.

Interestingly if you do save the file as untitled.bmp it's a perfectly
good bmp file.

The HTTP headers set by mongrel differ substantially from the ones set
by send_file.

Using send_file gives:

Status=OK - 200
Date=Tue, 16 Sep 2008 18:16:59 GMT
Server=Mongrel 1.1.4
Vary=Host
Status=200 OK
X-Runtime=0.01416
Content-Transfer-Encoding=binary
Cache-Control=private
Content-Disposition=inline; filename=16.jpg
Content-Type=image/jpeg
Content-Length=164553
X-Cache=MISS from www.sharehost.co.uk
Keep-Alive=timeout=15, max=100
Connection=Keep-Alive

Serving the file from the public area gives:

Status=OK - 200
Date=Tue, 16 Sep 2008 18:17:09 GMT
Vary=Host
Etag=48cfb25c-65c2f-918190
Last-Modified=Tue, 16 Sep 2008 13:19:24 GMT
Content-Type=image/jpeg
Content-Length=416815
X-Cache=MISS from www.sharehost.co.uk
Keep-Alive=timeout=15, max=99
Connection=Keep-Alive

Anybody know what I can do about this?

 Try using send_file's :filename option.

 Rails Wheels - Find Plugins, List  Sell Plugins - 
 http://railswheels.com

I already tried that but it makes no difference - the response headers 
are exactly the same. In fact in the one instance when explorer gets it 
right (when the file is served normally without using send_file) there 
is no content-disposition header and no mention of the filename in any 
of the other headers either.

Thanks anyway!

Thanks, but send_file already puts the correct Content-Disposition 
header in the response, but IE only seems to work properly when it's 
missing - but there are other differences in the headers, so I can't 
tell if that is significant or not.

Here is the response header that you get when the server sends a file 
from a public folder. It works properly with all the browsers I've tried 
-

Status=OK - 200
Date=Tue, 16 Sep 2008 18:17:09 GMT
Vary=Host
Etag=48cfb25c-65c2f-918190
Last-Modified=Tue, 16 Sep 2008 13:19:24 GMT
Content-Type=image/jpeg
Content-Length=416815
X-Cache=MISS from www.sharehost.co.uk
Keep-Alive=timeout=15, max=99
Connection=Keep-Alive

This is what send_file is producing. It doesn't work properly with IE -

Status=OK - 200
Date=Tue, 16 Sep 2008 18:16:59 GMT
Server=Mongrel 1.1.4
Vary=Host
Status=200 OK
X-Runtime=0.01416
Content-Transfer-Encoding=binary
Cache-Control=private
Content-Disposition=inline; filename=16.jpg
Content-Type=image/jpeg
Content-Length=164553
X-Cache=MISS from www.sharehost.co.uk
Keep-Alive=timeout=15, max=100
Connection=Keep-Alive

I did wonder if the doubled Status header is the source of the problem - 
but I've no idea how to get rid of it without abandoning the use of 
send_file.

if there was a way to get send_file to produce a response like the 
first one I'd be quite happy.

otherwise I'll just have to put up with it - it's not terribly serious 
just inconsistent.

Maybe I could make the controller create a publicly accesible symlink to 
the file, do a redirect to the same controller/action and then delete 
the link again.

I've been frigging about with this for 3 days now. Not feeling terribly 
Agile.
