That does not sound like the Home Page that you said it was rendering. Which controller action did you want it to run? Unfortunately you have not provided the other information I asked for, which was to show us a few lines round the Show Posts link in your code. Please provide that, unless posts#index is the action you want it to run. Also have a look at the html that the code is generating (View Page source in the browser, or something similar depending on which browser you are using). Copy/paste the relevant section here. But again, please look at it and see if it helps you to work out what the problem is. Again if posts#index is the action you want it to run then no need as that bit is working. > 2016-03-08T01:02:38.240308+00:00 app[web.1]: Rendered > posts/_navigation.html.erb (1.1ms) > 2016-03-08T01:02:38.240592+00:00 app[web.1]: Completed 200 OK in 8ms > (Views: 7.1ms | ActiveRecord: 0.0ms) That bit looks a bit odd as it only seems to have rendered what I assume is your nav bar. Perhaps this is the issue. If posts#index is the action you expected to be called but it is not rendering the view you expect then have a look at that code and see if you can see the issue. Otherwise paste the index action code here. But don't just post lots of stuff. Try and understand it first and any bits you don't understand then ask us for help.

Experience is good, especially comercial experience of Rails.

[Rails] Re: [Beginner] fields_for within each loop
It doesn't work as I expected.
I changed the controller and view but it doesn't work
in report_controller.rb
def new
...
QuestionSingle.each do |qs|
report.answer_singles.build ...
end
so answer_single generated as many as questions.
So when I call answer_singles in the fields for it calls every
answer_singles generated.
<% QuestionSingle.all.each_with_index do |question, index| %>
<%= index+1 %>. <%= question.content %>
<%= f.fields_for :answer_singles do |answer| %>
<%= answer.text_area :content %>
<%= answer.hidden_field :question_single_id, {:value => index}
%>
<% end %>
<% end %>
I have designed models not like report -> question -> answer
report -> answer (due to the predefined questions by scaffolding)
For all report same questions will be fed and answers have report_id,
question_id. My question is how I can use answer same as the
question_id.
Simple fields for shows all answer fields having same report_id.
Let me know if there's better design for predefined questions.
Thanks,
June

[Rails] Re: [Beginner] fields_for within each loop
I found from the development log that I'm passing question_single_id as
nil.
Seems to be my code of this part is not working
<%= f.fields_for :answer_singles, {:question_single_id => index} do
|answer| %>
<%= answer.text_area :content, {:question_single_id => index} %>
What I meat to do was to assign question_single_id when I fill the
answer :content.
And look up a text_area per each question.
Is there any good solution for text_area and fields_for usage?
I know I'm way far from CRUD development but what to do. (codes are
getting uglier)
What i should implement is like a quiz system with given questions.
User login -> answer the given questions -> end
Admin -> edit questions or review user answers -> end

[Rails] Re: [Beginner] fields_for within each loop
By making it nested_attributes I'm able to control it but still some
weird loop.
I don't fully understand how loop works in rails so please advise.
First this code makes one text area per each question.
<% QuestionSingle.all.each_with_index do |question, index| %>
<%= index+1 %>. <%= question.content %>
<%= f.fields_for :answer_singles, {:question_id => :index} do
|answer| %>
<%= answer.text_area :content %>
<% end %>
<% end %>
After I put answers and edit it makes number of answer text area same as
questions.
Please let me know how I can make the text area per question.
Thank you and regards,
June

Sorry, that doesn't make any sense to me. You might want to step back and document exactly what you're done so far, and post that and the code for the models you've (I'm guessing) created via scaffolding.

[Rails] Re: Beginner Help - Iterating and Displaying From Models with Relationship
Thank you very much everyone! Fred, your advise was spot on. Worked
like a charm!
<% Company.find(1).applications.each do |app| %>
<%= app.name %>
<% end %>
Perfecto!
Clint, thanks for the tip on the inspect function, I missed that. It
probably would have been the best way to debug and trial/error the
solution.
Once again thank you all for the help :)

That's not gonna do much good, as "puts" is going to output on the

Re: [Rails] Re: Beginner Help - Iterating and Displaying From Models with Relationship
Hi Ryan,
Your loop is correct. The issue how erb is interpreting what you are
asking it to do. The = is telling erb to spit out the contest of the
array Company.find(1).applications.each without running the block it
has. There are two ways to get it to display what you want. Remove the
= and change your block to read { |app| puts app.name } or do as
Fredrick suggested and write you code like so:
<% Company.find(1).applications.each do |app| %>
<%= app.name %>
<% end %>
Thanks,
B.

I am not at my computer, so I can't help out with code.
Basically you need to dig one layer deeper. The above is an
array of Applications. Try to <%=raise Company.find(1).inspect %> to
display
the returned value/array. From there you can play around till it
satisfy your needs.

Ok, so I've discovered that user.topics.build can be done in the User edit form (in my project, not in the gem). However, I'm not sure how to save this newly built topic; normally this would be done by the topic controller catching the POST right? But in this case it's not the topic controller that gets the POST. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks for the advice, follow up questions: I'm using Devise for authentication. I think this means the controller inside the Devise gem handles user model editing. So, how does one add Topics as a nested resource for Users? I understand this normally requires three things: a) nested partial form for creating topics owned by users added into the users edit form, b) @user.build_topic added into the Users controller edit action, c) accepts_nested_attributes_for :topics added into User model. So basically two questions: -is it standard practice to have to modify the gem like this (in the Devise controller)? is there a less intrusive way? -Are the steps that I required necessary & sufficient? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks again > > Alex Hi Alex, To simplify how you see those methods, you don't necessarily have to create a new user object. You can use: user = User.first .. and then look through the methods for the user object. The reason why I supplied two different puts statements is so that you can see the difference between methods for each. One is showing the methods available to the User "class", while the other is showing methods available to the User "object". Look for build_ methods as well as these will not save the record until you forcibly save the record. It will allow you a little more flexibility with your getting used to the console. Also notice that the create_ and build_ methods available to the user object are usuable with has_one relationships. While the same methods are usuable with objects from models that have belongs_to relationships. So, as an example: has_many :moderators has_many :topics has_many :posts has_one :userprofile You would see the create_ and build_ methods for a user object only for userprofile. user = User.first user.methods.sort.each do |method| p method end ... methods.. ... build_userprofile ... create_userprofile ... etc.. Likewise, for topic, if you had: class Topic < ActiveRecord::Base belongs_to :user #... end topic = Topic.first topic.methods.sort.each do |method| p method end ... methods.. ... build_user ... create_user ... etc.. Test out a brief example just to see what happens: topic.build_user As for accessing the table data for each model with has_one or has_many from the user model.. topics = User.first.topics And if you want to iterate over the returned array.. topics.each do |topic| p topic end -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks for all the replies. It looks like things changed after shutting down and starting back up the next day. My rails went back to version 2.3.5 for some reason. That would explain the different folder set I get when doing a "new" command. The Hartl book recommended having both Rails 2 and 3, in case I needed to switch back and forth. I installed RVM but am having a frustrating time trying to get the Terminal to recognize the command. I'm going backwards it seems :( If I had a .bash_profile, I don't now. I created one, put it in my home directory, and added the suggested RVM code to it: [[ -s "$HOME/.rvm/scripts/rvm" ]] && .

I'm not sure about the solution but maybe: Rails 3.0 was the first that used rails new app_name command. Previously it was rails app_name. Is that possible you tried first time with rails 3.0 or newer than second time used with 2.3.x? Maybe used the one click installer and got the older version. Maybe. Try rails -v.

[Rails] Re: Beginner to Ruby
Akshay, Personally, I liked Ruby on Rails: Up and Running (http:// www.amazon.com/Ruby-Rails-Running-Bruce-Tate/dp/0596101325). The reviews on Amazon are mixed, but let me say it this way: as a stand- alone book, it will not teach you the in-depth aspects of Rails development. What it WILL do is let you, in an afternoon, fire through an entire book and build an application quickly. I love the Agile Web Development with Rails book. Absolutely love it. But it's a decently large book that does take some time to get through because it covers all the bases. If you read the RoR: Up and Running book, learn the Rails environment and how these apps work, then go back and read the Agile book to get a deeper understanding, I think you'll be in good shape.

[Rails] Re: Beginner to Ruby
I started learning a little over a year ago. Although I have a long way to go, I can look back and see that creating an example app that was in the book (Agile Web Development with Rails, Third Edition), really helped me to learn what RoR can do. From there, I read through the details of the language while starting to build my own app. It's a slow process, learning while coding, and frustrating at times because it can take forever to figure out how to do the simplest thing BUT... slowly but surely, I'm learning. Whatever you decide to read, just stick with it. Good luck!

Thanks guys, I have been out of town a few days, thats why this late reply. I am using Rails 2.3.2 The book was published in 2006 so I guess the examples can be out of date. I ran into that when the book mentioned start-form-tag and end-form-tag... Took me a while to figure that out. Anyways, I am buildng all the examples from scratch, and so far I have not downloaded anything, so it could be a typo, even though I have checked the code several times...

He's using 2.3.2 from the errors.. So, did you create everything from scratch? Or, did you read a section in the book that said go to x website and download the incomplete or complete samples and you are working from those? If you are working from samples, the samples are probably not using the same RoR version you are. That's the very first question I'd answer.

[Rails] Re: Beginner: what to do after adding an association in a model?
So building on that example, you should add a column person_id to the address table. Rails will infer the foreign key based on rails model names. U can also specify the actual column by passing :foreign_key into belongs_to macro.

[Rails] Re: Beginner: what to do after adding an association in a model?
The associations you create in a model have to be backed up by the appropriate fields in the DB. For example: class Person has_many :addresses class Address belongs_to :person should be a model representation of the relationship inherent in the database (the two really go hand-in-hand). if: Table people id:integer first_name:string last_name:string Table address id:integer person_id:integer line1:string line2:string city:string state:string postal_code:string has_many :addresses tells Rails that for a given person, it can use that person id field to retrieve address records (those whose person_id matches the current person id value). Similarly, from an address, Rails can get back to the person record by following the person_id on the address. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Notice in this example that the first line in the people_controller is
commented out. So in this case Rails begins searching for an appropriate
layout by first looking in app/layouts/ for a layout template named
people.html.erb. If it exists Rails will use it automatically. If it
does not exist then Rails looks for a template named
application.html.erb. If that file exists it will be applied to any
controller that does not specify a specific layout to use.
In all cases if the layout is provided (by uncommenting line #1 in this
example controller) it will look for a template with the given name
(custom.html.erb) in this example.
I also provided a contrived partial in the
app/views/people/index.html.erb template to show when how how partials
might be used.
There is also a method called "content_for" I'll leave that up to you to
investigate, but this can also be very useful when dealing with layouts
and partials.

[Rails] Re: Beginner Layouts and Partials question
Those were really helpful posts -- I think I got the general idea, in which I should specify in the controller which layout it should belong to, and then in the layout file use <%= yield %> to render these views. I'll keep playing with it and see what comes up.

[Rails] Re: Beginner Layouts and Partials question
Here it goes A layout is like the container for the content(.. view) relating to your actions. When an action is called, the action renders its view. For example, the person controllers index action will look for app/ views/person/index.html.erb. It also looks for the layout it should render the view in. You can define the layout to use either in the controller (layout 'application' in your case) or put in in application.rb, which will then define a global default layout. You've got the right idea with the erb you posted. You can render partials in layouts, but for the action to render it's view in the layout, you need to put <%= yield %>. The entire contents of the actions's view will get rendered there. Your layout, application.html.erb should be residing in the app/views/ layout directory. You should add "layout 'application'" to your controller, add <%= yield %> to the layout, create views for your actions and try it out. Your views should render inside your layout. I hope that gives you some idea of how views and layouts interact. - John On Dec 23, 8:38 am, sa 125 wrote: > Hello - very new to rails and MVC, I'm trying to figure out how > layouts/partials co-exist.

[Rails] Re: Beginner Layouts and Partials question
right: you need an index-file for your index-action (actions and views pair up) wrong: it has not to be identical to the layout-file. try to put <%= yield %> into your layout instead of <%= render => :partial => @partial %> and change your index to Hello it's <%= Time.now %> in your controller just leave it like this def index end now, if you want to render a partial, do so by saying it for example in your view. if you put render :partial => foo in your controller, then by default layout => false is set. maybe i'm even mistaken somewhere, but anyhow i hope i could help. my suggestion: get hold of some rails basics. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Absolutely right. I want a single place which defines how I build
"fullname", so when I add title, middle name, whatever, it just works
everywhere I display.

Thanks a million for the response. Not sure what I did yesterday. I'm
pretty sure I wasn't referring to "@player", as I was in the Player
model object. Some foolish typo, I imagine. Glad to hear that I had
the right idea though.

You really want to have this in your Player model. It will look
almost the same:
class Player
def fullname
self.first_name + " " + self.last_name
end
end
or perhaps:
class Player
def fullname
"#{self.first_name} #{self.last_name}"
end
end

How did the method look when you tried to define it within your Player
model? If you still tried to refer to @player rather than self, that
may be your mental hurdle. You're defining a new attribute of a
model. The rest of the system shouldn't care if the storage behind
the model changes to hold the fullname and the other methods become:
class Player
def first_name
self.fullname.split(' ').first
end
def last_name
self.fullname.split(' ').last
end
end
(NOTE: I'm not suggesting that this should happen, but only that the
rest of the application can continue to reference @player.first_name,
@player.last_name, or @player.fullname without having to know what
really sits behind the model.)

[Rails] Re: Beginner Question: Formatted Text Data -> Hash -> Database.
I'll be interested to see what responses you get, but I can't think of a more
efficient way. I'd try something like:
my_file.each_line do |line|
if line ~= /$User/ and this_user.username.length > 0 then
if this_user.save then
puts("Saved user #{this_user.username}")
else
puts("Problem saving #{this_user.username}!:\n#{this_user.errors}")
end
this_user = User.new
end
attribute, val = line.split(/:\s*/)
this_user.send(attribute.lower, val)
end
That's air-code obviously--may be wildly off...

Subject: [Rails] Beginner Question: Formatted Text Data -> Hash -> Database.
I have a text document that has formatted data in it, and I am attempted to
determine the best way to parse the data to break it up into hashes that I can
then write to my databases. I suppose my issue is determining where to tell
Ruby to STOP reading in data to write into the database. The file would be
similar to this:
User: Username
Phone: Phone number
Address: Address
Comments: Comments
Data1: Data
Data2: Data
Data3: Data
User: Username
Phone: Phone number
Address: Address
Comments: Comments
Data1: Data
Data2: Data
User: Username
Phone: Phone number
Address: Address
Comments: Comments
Data1: Data
Data2: Data
It's not that difficult to chomp the \n and use a split to create a hash in a
loop, but how do tell Ruby to start a new database write process if it hits a
new "user" key value? Should I write a case statement to check each line for a
"user" key and use that line to call a new instance of my database
class/method? Is there a faster or more efficient way?
