[Rails] Design Question - re: Polymorphic association
Curious about the best direction or design pattern to use here - looking for opinions. I have a store with products diced into categories. Should I create a polymorphic model 'Product' and have individual models for the product types? Reason is - the products differ quite a bit in columns/profile etc... I could keep in one table but feel it will get horizontally fat quickly as these different product types get modified. Question is - I'll need to access these different products so would I simply delegate attributes to the Product model so I can access each related model's attributes? For instance, I'll need to fetch all of a certain type through the Product model. I guess I could use STI for this but seems polymorphic would perform better. Appreciate any feedback on whether this is practical or way off. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] beginning web development with ror, how?
Hi everyone, I just realized that on my shared web hosting, RoR is supported. What to expect from this in terms of developing a simple HTML5 web page to advanced portal that includes forum board and mailing list? How do I begin. I have a shell access to this hosting, but not as root. P/S: I'm not really a programmer, more of a sysadmin although I had learned a bit of programming (java, c++, python, bash scripting php) during my schooling years. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Re: [Rails] Re: ROR and Drupal
I think you are doing in a wrong way. Drupal is a complete CMS and not worth being called from ROR. If it is the other way round, ie, Calling RoR from Drupal will be not only useful, will make the website more maintainable. All you need to do is make RoR webservices, then make some drupal modules to attach the RoR feeds into drupal.

[Rails] Need to add path to routes.rb
Dear Folks, I am Web developer and have experience mainly with the Django Web framework for Python and wish to learn ROR. I am currently using Rails 3.0.3 and was getting a routing error whenever I added a view to a controller until I found out I had to add the path to the routes.rb file under the config directory. Is this new in Rails 3? I am asking this because I was following the example in Agile Web Development with Rails 3rd Edition which uses Rails 2 and getting the routing error. I also find that if use the rails generate command the routes.rb file is automatically updated. Does this mean that the proper way to create views and controllers is to use the above command. If so how do I create a view function in an existing controller without having it being overwritten or is the manual way the only way to do this? I hope that is clear.

Re: [Rails] saravanan
Use javascript to achieve your goal.
I have used jQuery library.
$(function() {
$(#list_box_id).live(change, function() {
var e = $(this);
var selectedValue = e.val();
e.hide();
$(#input_field).show().find(input).val(selectedValue);
})
});
this is not the perfect solution you have to code it according to ur
requirement.

[Rails] Re: Which RoR to run on Mac OS X for a particular RoR app.
No, 2.3.5, 2.2.2 and 1.2.6 are still installed as noted above Whoops. Yeah I bought two books on RoR and google like crazy to find help and information. The tutorials online assume one is pretty much up to speed kind of like a cooking show half way in (what white sauce we just made?) The books deal with programming fairly well but not the config stuff - especially Mac. I would just feel 100% more confident going into getting this app running if I knew the environment was clean and pure. And only one version of the software loaded. As you mention this stuff changes a lot. For example why is rails -v not working. As you said the command left the other versions. BTW, I do not agree that this is merely a time issue. I programmed on C on a PDP when there was exactly one book. Writing and compiling C is a piece of cake compared to RoR. So I appreciate asking why, but I would just love a how. How do I blow away all RoR completely and then I think a gem install of version 2.2.2 would work. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

RobsMacAir:~ rob$ gem uninstall my_gem -v=2.3.8 ERROR: While executing gem ... (Gem::InstallError) Unknown gem my_gem = 2.3.8 Sorry, I forgot to tell the group to e-mail me updates on the post. I'm sorry, Colin is right, what I wrote was just an example. I expected after deinstalling rails 2.3.8 gem list local would find the other rails versions. But did this blow away all rails? The gem command is being cautious. It doesn't want to delete anything but the absolutely necessary. I personally would not want to remove a gem and find out that the command blew away 10 other gems just because they are either required by the one I just deleted or compatible with it. What if I wanted to keep them because they serve me for other purposes?

What _is_ confusing is that there are so many out of date tutorials and mailing list archive entries that are found when searching for data on rails. This is inevitable unfortunately if you want to experiment with fast moving technologies like Rails. All the ones you mention have been little changed for decades so the documentation is stable. +1 with Colin here Is there a way to just go into the file system, and delete all the directories for Rails and just do a fresh reinstall. I cannot figure out rvm, After reading an entry on the internet I tried just that a week or so ago as the entry specified that it _might_ be possible. However, after I blew away all folders in the gem directory and asked for the gem list all the gems were still there and I had to run the commands manually anyway to make sure everything was gone as it should. I didn't want to have problems during re-installation. You're going to need to uninstall the gems manually and probably selectively I'm afraid, but if you find a way to do it all at once, please let me (us) know. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Re: Proper way to back out a bad migration?
Typically I do rake db:migrate VERSION=0 But that also gave me the same error about Primary key is not allowed in a has_and_belongs_to_many join table So I then fired up dbconsole and manually dropped the table. But now I even if I run rake db:migrate the join table isn't created - probably because it 'think' it had run it previously. I believe the problem you've been running into is that your schema migrations table still has the number of the migration(s) you removed manually. When the rake task runs it sees the numbers there and says OK, that one is done so it skips the migration. I think the best thing to do in that case is to manually delete the record(s) in the schema migrations table in order to be able to rerun them. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

I believe the problem might lie in leaving the '=' sign out of the command: gem uninstall rails -v=2.3.8 (what I would have typed) vs. gem uninstall rails -v 2.3.8 (what you actually typed) I'm not sure, but *maybe* you had 2 different versions of 2.3.8 installed (if that is possible)? I guess it's possible that when you answered with option 3 it went out and blanketed out the rails versions and now you don't have any of them. :( If that is the case and since you need rails installed you can install it by just specifying the version you want: gem install rails -v=x.x.x (replace the x.x.x with the version you need). That should install any other dependencies it might need if you still don't have them. If you have problems or more questions I think it might be helpful if you post the list of gems you have now to give us a better idea about what mismatches you could have. There is something you should know I am not sure you are aware of. Different versions of Ruby and Rails have different dependencies. For example, a given version of rails might need a minimum (and maybe maximum) version of activerecord. Just having _any_ version of activerecord will not do. In my opinion the best thing you could do if you want to have a clean environment is remove everything you have and install what you need. The process *shouldn't* be difficult. I believe the prior mentions to RVM were meant to indicate to you that there are ways of keeping separate environments if you need them. For example, you might have an application that runs under Ruby 1.8.6 and Rails 2.3.5 and another one under the latest Ruby and Rails versions. The activerecord and related gems you need are going to be different for sure for between both environments. RVM will help you to keep those 2 environments separate. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

needed, but I have been doing it this way since early this summer.
Later, you can access that version of the file as you would any other
paperclip-attached model attribute. In this example, this might look
like document.pdf.url(:text). Your untouched original will always be
at document.pdf.url(:original).

[Rails] Re: Which RoR to run on Mac OS X for a particular RoR app.
Robert Walker wrote in post #966886: Rob Th wrote in post #966852: I expected after deinstalling rails 2.3.8 gem list local would find the other rails versions. But did this blow away all rails? I admit I am in learning mode. I thought this was a place to help out beginners. I have been programming in Assembler, C, and tons of SQL and now some PHP and writing shell scripts since the late 70s, and the complexity and impreciseness of the books and tutorials are amazing RoR, Is there a way to just go into the file system, and delete all the directories for Rails and just do a fresh reinstall. I cannot figure out rvm, Hopefully this will help clear things up for you. The installation of Ruby on Rails on Mac OS X is a bit different than on other platforms. A version of both Ruby and Rails are pre-installed either with the operating system or Xcode (not sure which since I always install Xcode on all my systems). Some (usually older) versions of a number of gems are installed in the Mac OS X system library (/System/Library/). The gem command (even using sudo) cannot be used to uninstall these system gems. It might be possible to use the root user to delete the framework that contains those gems, but I don't know what you might break in doing so. With RVM you can effectively replace all the pre-installed system gems with gemsets that you can fully manage. Installing and learning RVM is actually easier than trying to manage the system installed gems (including the Rails ones). I tried rvm and I just don't get it. Sorry. I think you are right. I think Xcode installed some of this. Actually I do not recall any other install. I was pretty surprised to see all these versions. Not sure where they came from. This whole RoR thing makes me nervous. I own a bunch of heavy equipment and I have operators and mechanics. Most RoR types are users, not mechanics. I think I am leaking hydro and need a wrencher not an operator. :) I appreciate your help. I did de-intall xcode last night using the script from Apple and it did not clean this up either. Can you explain why after doing a de-install of 2.3.8, ruby -v says no ruby? See above.

Different versions of Ruby and Rails have different dependencies. For example, a given version of rails might need a minimum (and maybe maximum) version of activerecord. Just having _any_ version of activerecord will not do. Thanks. I am pretty sure this is true. Some people think that is a good thing. I am not so sure. In my opinion the best thing you could do if you want to have a clean environment is remove everything you have and install what you need. That is where I got started. But instead people are trying to convince me to keep multiple versions, but if this is screwed up why? The process *shouldn't* be difficult. I wish I could figure out how. Not just what tool to work. I believe the prior mentions to RVM were meant to indicate to you that there are ways of keeping separate environments if you need them. No kidding. For example, you might have an application that runs under Ruby 1.8.6 and Rails 2.3.5 and another one under the latest Ruby and Rails versions. The activerecord and related gems you need are going to be different for sure for between both environments. RVM will help you to keep those 2 environments separate. I only need one environment ruby 1.8.7 and rails 2.2.2.

We are all trying to reach out to you and offer the slender twig of RVM because we also suspect you want to do this without hobbling your machine to more modern versions of the Rails framework. Once you do get this application up and running, you're probably going to want to develop something else in Rails 3, and that requires at minimum 1.8.7 of Ruby.

[Rails] Re: Design Question - re: Polymorphic association
Hi Randy, Hard to say for sure without knowing the specific needs/requirements/ demands of your app, but... if your app is a typical biz or ecomm app backed by an rdbms where most of the usage (for end users and for analysis) of the app is spent doing reads vs writes, when it comes to the design of the db, ime, regardless of caching strategy, I always try and error on the side of faster reads (and slower writes) vs faster writes (and slower reads). So, assuming a read-dominent app, if you're asking should I go with one table for all products, or one table per product type?, if I were the developer, I'd probably go with the one (wide/sparse) table strategy. I'd define/handle the different needs/rules of the various product types in app model(s) code, but have the Product model ob handle core persistence of all of those various types of products (stored in the products db table). The less round trips to the db, the less joins in the db, the more denormalized the db, the more indexed the db, ... all of these should help make direct db reads faster (at the cost of slower writes on such wide/sparse/denormalized tables).

[Rails] Re: missing attribute during initialization
Sorry for the late answer ... I had to simplyfy my model somehow to really test that is not an other interaction that causes that problem. That seems very strange. Are you absolutely sure that this what is happening? valid? cannot be fetching the object from the db as it must exist before you call valid? Or are you talking about fetching associated objects that are checked within valid? Do you have a repeatable situation where you see it? Yes, I guess so. My Model: class MyModel ActiveRecord::Base after_initialize :init_token validates :token, :uniqueness = true def init_token puts init token if self.token.blank? self.token = ActiveSupport::SecureRandom.hex(10) end end end And a simple case where it happens: m1 = MyModel.create m1.token.should_not be_empty m2 = MyModel.new m2.token.should_not be_empty m2.token = m1.token m2.valid? # where the exception is thrown (also init token is called) Full trace below. If so what happens for example if you use ruby-debug to break in just before the call of valid? and then inspect the object and call valid? from the console. I never used the debugger yet, but I will try to. But maybe you already know of the above info what is going on here?

[Rails] style question: update or create active record
I find that I'm frequently writing code that could be described in
english as If there is an incumbent ActiveRecord that meets some
specific criteria, then update one or more of its fields. Otherwise
create a new record with the same criteria and new field values.
ActiveRecord's dynamic finder methods (find_or_create_by_xxx) are not
usually expressive enough to do this. But I haven't been able to create
a general method that smells right. It's been bugging me, so I turn to
the mavens of style in this forum for suggestions.
As an example, I just wrote this monstrosity:
def set_xattribute(name, value)
symbol_name = self.class.intern_symbol_name(name)
incumbent = SymbolValue.
where(:symbol_values = {:symbol_name_id = symbol_name.id}).
where(:symbol_values = {:owner_id = self.id}).
where(:symbol_values = {:xclass_id =
self.class.xclass_id}).first
if (incumbent)
incumbent.update_attribute(:value, value)
else
SymbolValue.create(:symbol_name_id = symbol_name.id,
:owner_id = self.id,
:xclass_id = self.class.xclass_id,
:value = value)
end
end
Note the huge amount of repetition between the finder (incumbent =
...) and the creator (SymbolValue.create(...)). I can think of a few
approaches to DRYing this code (e.g. scopes), but what do the mavens of
style in this forum suggest?

yes... what if the user-supplied search word is only one name, or three names?
The solution to the problem that I use is this snippet (where value
is a user-entered search value, and the following chunk of code is
just part of a larger search/sort/order query, but all the important
parts are here):
conditions_sql = []
conditions_values = []
value.split( ).flatten.uniq.each do |name_part|
conditions_sql (people.firstname LIKE ? OR people.lastname

3.times {conditions_values %#{name_part}%}
end
conditions_values.unshift conditions_sql.join( AND )
Person.find(:conditions = conditions_values)
(And after looking at it for the first time in ages myself; as Marnen
points out, I could probably replace the 3.times do ... bit with
named placeholders to streamline it a little more.)

[Rails] Re: Advice on data design idea
Correct I would like to support multiple parents per a given category. For instance: Automotive Trailers Cargo Trailer Marine/boating Misc. Cargo Trailer 'Cargo Trailers' may be accessed through different hierarchies. I have considered using a graph but through the implementation may be a bit overkill or complex. Curious if somehow to do this via awesome_nested_set or ancestry? btw - thanks for the help.

I have an automotive site that needs to have shared categories. I've checked out different nested set, ancestral, acts_as_tree, acyclic plugins but feel they don't exactly fit. As I said in your other thread, programming is not about what you feel. So I am about to roll my own simple solution. Any feedback as to whether this looks good is appreciated. Essentially I have: Sections - Automotive, Marine, Air Groups - Cars, Trucks, Bikes Categories - Pickup, SUV, Utility Truck The categories need to be able to be under multiple groups and/or sections. In what way do you mean this? Will you actually have multiple parents for one category? Can you give an example of the way your hierarchy will look. So I am thinking on having a series of HABTM associations: sections_groups sections_categories groups_categories This will allow me to add new groups/categories/sections with highly flexible associations. @section.groups or @section.categories etc... Does this seem right or am I way off? I'm also concerned whether it will perform well.. I think you're way off. Sounds like you have a hierarch which is either a tree or an arbitrary graph (not sure which, pending your answer to my question above). In either case, all you need is one model (call it Category). Use awesome_nested_set if it's a tree. Done. If it's a graph, things might get a bit harder, buthttp://www.artfulsoftware.com/mysqlbook/sampler/mysqled1ch20.htmlmay give you an overview of what you could do.http://www.dweebd.com/sql/modeling-bidirectional-graph-edges-in-rails/ is a Rails-specific implementation of one of those ideas (though it implements bidirectional edges and you probably only need unidirectional ones).

Please quote when replying. Randy Clark wrote in post #966962: Correct I would like to support multiple parents per a given category. For instance: Automotive Trailers Cargo Trailer Marine/boating Misc. Cargo Trailer 'Cargo Trailers' may be accessed through different hierarchies. Er, why? Why does a cargo trailer belong in a boating category? I have the impression, here as in your earlier post, that your category hierarchy may be in need of some normalization. I have considered using a graph but through the implementation may be a bit overkill or complex. How can it be overkill? It's the exact data structure you're talking about. Will it be complex? Yes. If you could normalize your categories so that each has only one parent, you'd have a tree, and that would be a lot easier to implement. (Whether you can in fact do this for your data is another question.) Curious if somehow to do this via awesome_nested_set No. That only allows for each node to have one parent. or ancestry? I've never heard of that one. However, having looked up the docs, it appears that Ancestry uses the materialized path pattern. That generally only supports one parent per node; it's another way of doing trees. Unless you can make your data into a tree, you need a directed graph structure. btw - thanks for the help.

def self.create_or_update(attrs_to_match, attrs_to_update = {})
if (incumbent = self.first(:conditions = attrs_to_match))
incumbent.update_attributes(attrs_to_update)

[Rails] Re: Render partial generate unwanted spaces
I'm not sure it's the editor; my own issues are coming with Notepad+ +. Still, I'm glad I checked back into this thread. It's given me some stuff to try out. If I find the magic solution (or if I don't) I'll check back in. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Re: Advice on data design idea
Thanks Marnen - Er, why? Why does a cargo trailer belong in a boating category? I have the impression, here as in your earlier post, that your category hierarchy may be in need of some normalization. I may need to rethink the data structure, but as of now the site calls for categories to be able to be found under multiple sections. Customers sometimes search for items under different categories kind of like aliases. So in the case of the cargo trailer its definitely automotive, but some marinas may be used to finding tool/cargo trailers within the marine category. Rather than have duplicate categories, it would be best to share the same category. How can it be overkill? It's the exact data structure you're talking about. Understood but after looking into various DAG databases and methods I think it would be better to find a way to normalize or restructure the data to utilize something better supported such as one parent per node setup such as awesome_nested_set or ancestry. I am wondering, what about simply manually defining the categories for my root sections? For instance: automotive = [cat1, cat2, cat3, etc...] Essentially create 'virtual' sections. This will keep my categories simple yet allow me to 'group' a category into multiple virtual sections when the needed. Can I get an amen or should I go stand back in the corner? :-) -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.
