I am using Rails 0.13.1 and typing:
script/generate scaffold Student
I am getting:
The name ''Student'' is reserved by Ruby on Rails.
Please choose an alternative and run this generator again.
Suggestions:
Sense 1
student, pupil, educatee -- (a learner who is enrolled in an educational
institution)
=> enrollee -- (a person who enrolls in (or is enrolled in) a class or
course of study)
Sense 2
scholar, scholarly person, student -- (a learned person (especially in the
humanities); someone who by long study has gained mastery in one or more
disciplines)
=> intellectual, intellect -- (a person who uses the mind creatively)
---
What problem rails have with ''student'' exactly? I
don''t like any of those
suggestions, is there a workaround?
Thanks in advance
Hi Moshe, For me it worked well. Also I have seen some samples using ''Student'' class in Rails API: http://api.rubyonrails.com/classes/ActiveRecord/Transactions/ClassMethods.html Eszter Moshe wrote:> I am using Rails 0.13.1 and typing: > script/generate scaffold Student > > I am getting: > The name ''Student'' is reserved by Ruby on Rails. > Please choose an alternative and run this generator again. > > Suggestions: > > Sense 1 > student, pupil, educatee -- (a learner who is enrolled in an educational > institution) > => enrollee -- (a person who enrolls in (or is enrolled in) a class or > course of study) > > > Sense 2 > scholar, scholarly person, student -- (a learned person (especially in the > humanities); someone who by long study has gained mastery in one or more > disciplines) > => intellectual, intellect -- (a person who uses the mind creatively) > > --- > > What problem rails have with ''student'' exactly?

This can be the case, for instance, if you have loaded/required your Student class already in your environment.rb.

It works fine for me too. Are you sure it is not a practical joke or something? ;-) Gennady. Biro Eszter wrote:> Hi Moshe, > > For me it worked well.

Do you have anything else named "student"? I''m too new to know what SHOULD conflict, but maybe the database name, since that''s in ActiveRecord too? Or both singular and plural tables?

I installed rails on another computer (running Windows this time) and creating those scaffolds worked. I''ll have to see what''s wrong with rails on the Ubuntu box, if anyone got ideas, let me know. Thanks

This is happening because you already generated the model and controller. Once you''ve done that, it''s treated as a reserved word because they already exist. The scaffold generator creates the models, controllers, and views for you. Try running it alone instead of generating the controllers and models first. Ben
Is this a good idea for certain gui apps? I am writing a debugger, so need to scroll code, single-step, highlight, and display variables. The above seems like a piece of cake for Rails, except on scrolls, mvc model returns to server, classicly. Any opinions on using Ajax to scroll text, etc? There is a huge incentive to use Rails as a general GUI: Only one learning curve to learn. Any opinions? -John B
How are you thinking of using Rails? It''s a web framework. I guess you might try something with Ajax calls and such, but it seems like you would have extremely overcomplicated code. You''re not interacting with a database really, so active record wouldn''t help you. Did you have a specific approach in mind? I''m curious to see what you are thinking?

Well, a debugger is client-server in the sense that the control comes from the person doing the debugging. The model can be the debugger code itself. The coordination of code view and model is very naturally done by the controller. Look at it this way: The MVC architecture plus GUI (CSS) is very strongly implemented in Rails. Not to mention the generator, which as you know can be modified. Its definitely X-platform. Finally, the know-how does double-duty as web and GUI together. Its this last factor that''s a real clincher for me - at least makes me try to see if Rails can do double-duty. Ah well, on to learn FXRuby...
