Re: [Rails] How to define virtual attribute for date_select drop menu using active model
I have never done this. Just trying to help. I think the problem you're having is that your field doesn't have a date compatible value. If you check it's class it might be NilClass. Since the fields does not belong to a table date_select probably has no idea what to do with it because it doesn't have a 'type'. Have you tried to give the field a Date compatible value before your view is executed, just to try if the view works? Also, maybe type_cast (in ActiveRecord::ConnectionAdapters::Quoting: http://api.rubyonrails.org/ ) would help?

You don't need to specify att_accessor for fields in the database, ActiveRecord will supply them automatically. By providing them yourself you have disabled the automatic ones.

[Rails] Re: Best practice on Javascript and rails
This might not be what you're looking for but I'd start by reading up on the Asset Pipeline http://guides.rubyonrails.org/asset_pipeline.html.

Very annoying, and I'm sure if I just knew the right way to organise everything it'd be much easier.

What does that mean? Are you saying that the html element for the file upload doesn't have a name attribute? Well, then give it one.

[Rails] Re: Pagination doesn't work with will_paginate. Could anyone help with this?
It's been a while since I have setup anything with will_paginate but if I have it in my models it is because I followed some instructions from somewhere, probably either railscasts or the gem's documentation itself. It could be that things have changed since I used will_paginate for the last time but I am pretty sure that your model should 'know' somehow that it can be paginated.

[Rails] Re: Duplicate Record Detection
I don't believe you're going to find a magic formula for what you're suggesting. The same thing could be said about last or first names as you are suggesting could happen with SSNs. What if somebody misspells Smith for Smit, for example? But worse yet, what if it is not a misspelling situation and the Smit is actually Smit? The same is true for SSNs, switching the last 2 digits does not mean it was a misspell, it could just be that 2 different people have the same name and very similar SSNs. You have to draw a line somewhere, I think. You could use auto-complete fields and then provide options based on records found using the 'LIKE' option in the where clause using the information currently being entered.

[Rails] Re: Duplicate Record Detection
Whenever I have worked on similar projects in ended up being the customer's idea of what a close approximation was that made a possible duplicate. It was usually something like: same birth date same last name same city (optional) same state (optional) Since there is not such a thing as a tried and true method for what a duplicate record is I believe you'll just need to do some manual work.

Hi,
I am working with a project where I am writing the following code:-

store_fb_other_information(profile_obj, book, fb_books, provider,
:book, profile_obj.book_information, BookInformation)

Can I refactor the above code using metaprogramming If yes how?
Hi there. I hope this helps...
I think you could make this work several ways but in any case it looks
to me that you only need to pass to store_fb_other_information a
couple of things to make this whole thing work. For example:
store_fb_other_information(profile_obj, provider, model) # where model
could be an instance of Activity, Book, etc. if you have them
or
store_fb_other_information(profile_obj, provider, ModelName) # where
ModelName could be the class name for Activity, Book, etc. if such
models exist
or
store_fb_other_information(profile_obj, provider, ModelInformation) #
where ModelInformation could be the class name for
ActivityInformation, BookInformation, etc. which seems to exist
or
store_fb_other_information(profile_obj, provider, model_name) # where
model_name is a string such as 'activity', 'book'
My preferred option would be the first one (if those models actually
exist and you instantiate them) because it would be the easiest in my
opinion. Any other option would be a slight variation on this one,
though. So say you have an activity object:
store_fb_other_information(profile_obj, provider, activity)
def store_fb_other_information(profile, provider, model)
# if you need the second parameter as a string
model_name = model.class.to_s.downcase
# if you need to get to fb_activities
model.send(fb_#{model_name.pluralize})
# you already have provider
# if you need the model name as a symbol
model_name.to_sym
# if you need to get to the profile_object.model_information
profile_obj.send(#{model_name}_information)
end

[Rails] Re: Autocomplete plugin
If I understand well the question the answer should be yes. If what you mean is if it is possible to use one field on a page to find data in more than one column in the table it should be possible the only thing you would need is to query the table by the columns you desire to query on.

[Rails] Re: Constants and Configurations
I believe I know what you are trying to ask. I had to setup something similar for an application of mine. I have one table with one column for each value type (boolean_value, string_value, integer_value, decimal_value and datetime_value) and a 'code' column for values such as 'timeout minutes'. In my maintenance pages I have the code field and 5 other fields, one for each column type. So far I have not used the datetime_value field but you never know. I validate that one and only one of the value fields is entered and make sure that if the chosen field is the boolean_value one it is either true or false to avoid mistakes such as the user not entering any values on the screens and pressing Enter. Another thing I am doing for security purposes is that once the record has been created the user must 'unlock' the code field in the editable pages to be able to change it and when he/she does an alert is displayed saying that if the code value is changed the application might stop working. I hope this helps. On May 8, 6:08 am, Tiago Veloso ti.vel...@gmail.com wrote: Hi, Right now I have some Constants in my application that serve as configurations for my application.

[Rails] Re: Rails: Developing on Win7?
I have been developing in Windows for a while now and it's true that there is no much support or love for it in the RoR world. If you really want to keep going with Windows, though, if I were you I would get the rubyinstaller and DevKit right away from http://rubyinstaller.org/downloads. To install DevKit follow instructions at https://github.com/oneclick/rubyinstaller/wiki/Development-Kit. Most of the problems I have had working with Windows were because of the DB adapters. To work with MS SQL you will need 2 gems: activerecord-sqlserver-adapter ruby-odbc Working with MS SQL you will probably want to stick to ODBC so you will need to create a System DSN. In Windows 7 first try to create it the regular way but it probably will not work. If it does not work then you will need to delete what you just created and then use the executable at C:\Windows\SysWOW64\odbcad32.exe. This is the 32-bit version.

I see 2 things that might help you.

[Rails] Re: Saving records from multiple tables
You say to use a transaction... I already am using a transaction! Sorry about that. I obviously didn't read carefully your post. The issue is that if the person save succeeds and the client save fails then the transaction is rolled back fine. However the person record now has a person.id and subsequent code assumes that the record is saved and tries to refind the record which of course does not exist. I have got around this by saving the original value of the person.id and then resetting it in the rescue clause but it is a bit messy. One other issue is that the only validation errors that get set are the errors from the first record (person) that is saved so the user may fix these up only to find new validation errors from the second record... I have not tried before what you are trying to do but I will as soon as I have some time to spare. I don't understand why Rails would not clear the ID value of the record and reset the record in order for new_record? to return true. I'm sure there must be a tidy way! If you use acceptes_nested_attributes_for and field_for the validations will work just like you want them to work, however you will need to change your form to be based on your person model, which based on what you have explained would be pretty much impossible since the person is selected in the form and you don't have a person object to base the form on. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Re: unpacking ruby-odbc
What 'native extensions' means is that parts of the gem are not written in Ruby but are (generally I think) in C. These need to be compiled to generate code suitable for the OS the app is being run on. Yes, I learned that by working with ruby-odbc. The gem cannot therefore be frozen as it would be frozen with code compiled for the wrong OS. I think therefore you must install such gems on the target machine in the normal way. Thanks Colin.

[Rails] Re: created_at, updated_at and MSSQL
So there is never any ambiguity about timestamps in the database. For example, suppose you move to a server in another timezone, it can get very messy if you have timestamps in EST or whatever happens to be your local timezone today. By keeping all timestamps in the db in UTC you will always know what they mean. I understand the benefits of UTC, however... Normally Rails will do the conversion to local time for you so the fact that it is UTC in the db is not something you need normally worry about. This is the reason why I noticed. I have to display on screen the date and time from updated_at and I saw that while my local time was around 4:00 PM the screen was displaying around 9:00 PM. In other words, there is no 'conversion' going on. I don't know if it makes a difference but when I display the values I am not displaying the full value of updated_at, I have to break it down in 2 values, date and time, and I am using strftime to do the job. Should I be using something different and/or converting the values to local time first somehow? -- 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? Removing gems is a little boring but it shouldn't take you more than 10 or 15 minutes to remove all the ones you need to remove once you get the hang of it. I admit I am in learning mode. I thought this was a place to help out beginners. Absolutely. I have had great help in this forum from day 1. 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, I can't say that I agree with you here. 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.

[Yn] Removing rails Successfully uninstalled rails-2.3.8 RobsiMac:~ rob$ rails -v -bash: /usr/bin/rails: No such file or directory I seem to have messed up somehow. (i.e. I expected after running sudo gem uninstall rails -v 2.3.8 I would get rails -v saying the next most current version.) 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.

[Rails] Re: Which RoR to run on Mac OS X for a particular RoR app.
Never, this is the one and only rails app ever. I do want to get 1.8.7 on this machine and rails 2.2.2 to match the source machine. I would actually like to eventually find a programmer to convert it off rails. If you are thinking about getting a programmer anyway maybe it might be wiser if you get one now to get your RoR environment straight and your application running as it should. If what you are unhappy about is the trouble you're having with it, you not being an expert, but the application is doing what it is supposed to at your satisfaction when the setup is correct I think converting the application might be a mistake. You probably will end up spending a lot more money rewriting the application than paying somebody to get your application environment straight.

[Rails] Windows new installation - Always problems
I would like to know if there is a way to 'package' an application with all the associated gems and ship it to a new server and having it to just work in a Windows environment. Although I have never done it I know that Rails can be frozen into the application. I am wondering if I can do the same thing with other gems. I have found this (http://gemsonrails.rubyforge.org) that seems to be what I need, although it's from 2007 and I was wondering if anybody is using it and/or there are other or better alternatives. Since I can't use RVM I have looked into Pik but that, I believe, will not help me since it's a way to keep environments separate, not 'package' the application as I need it. Also, would it be possible to include Ruby and Mongrel in the 'package'? That would be just great. Any help would be greatly appreciated.

[Rails] Re: Windows new installation - Always problems
I looked into JRuby some time ago. What would that buy me in relationship to 'packaging' the application? Well, you could compile the whole thing as a WAR file and deploy it as a Java servlet. Glassfish supposedly gets you similar benefits without needing to compile. I don't use JRuby for Rails, but I understand it tends to be the easiest way to get things working on Windows. Thanks Better yet, don't deploy on Windows. You couldn't resist, could you? :D No. Why do things that are painful if a known non-painful way is available?

[Rails] Re: Windows new installation - Always problems
Many will dis it but I have found Instant Rails well suited to exactly that (if you have to work in windows). The latest version of Instant Rails is old and uses Rails 2.0 or so it can be upgraded using gems (look on this list for problems with that other have had) to at least 2.3. I do not know the score on 3.0 as I have not gotten there yet. IR integrates all of the stuff for ROR including Ruby, the db server (mysql) and mongrel (I think, if not you can install it using gem install) You can just freeze all of your gems and away you go. I had not thought about IR but it actually would not work in this case, I think. To make the whole picture even better the client will not only use Windows but MSSQL as well, which is how the whole mess started actually (ODBC problems). In order to use MSSQL I have to install some gems that need the DevKit and DevKit needs Ruby to be installed with the Rubyinstaller (if I remember the name well). That would probably not work (I could be wrong) with Ruby installed from IR. Also the Rails version will probably need to be upgraded to make all our applications compatible. Manually installing Ruby and Mongrel and then freezing gems into the application might be the way to go here. I'll be trying out Marnen's suggestions for that and I will also try to replace the ODBC dependency with something like 'tiny_tds' and see how that works.

Then do what we're doing here: use a separate *nix server for the Rails app, and connect with TinyTds. That way Rails and MSSQL both get the environment in which they're happiest.

[Rails] Re: Which RoR to run on Mac OS X for a particular RoR app.
To uninstall a gem version you have 2 options: a) Declare the version at the end of the uninstall command: gem uninstall my_gem -v=x.x.x (You replace the 'x.x.x' with the version you want to remove, OR b) Run the uninstall command without version specified: gem uninstall my_gem Option b) will prompt you which version you want to remove out of all the versions you have loaded but if you only have one version it will go ahead and remove just that one without asking. Just a note about the 'what you wants'. I don't know if it will be your case but I'm not a native English speaker and when I first talked to native speakers it bothered me a lot the 'no, what you want is...', then I realized that it's just their way of saying 'what you probably should do is...', or I take it that way.

[Rails] Re: Update div with Prototype
Hi,
I have not used Rails 3 yet and I see by your link_to helper that's
what you are using. Sorry if I can't be of much help, but I'll try to
point out what I see here that _could_ be wrong.
div class=menu_activado
% = link_to Link, about_path,: remote = true%
/div!-- fin sub_cabecera --
I am assuming the first div is missing the opening '' because of a
mistake while copying the code?
A quick look at the Rails 3 API does not show how to indicate that you
want to update an HTML element's contents. Compare the link above with
the following, based on Rails 2.3.5:
%= link_to_remote 'Get Time',
:update = 'current_time',
:url = {:action = 'get_time' },
:complete = visual_effect(:hightlight_shake, :current_time) %
div id=current_time/div
Notice the :update line? It indicates what HTML element to update with
the contents returned by the server. I can't see in the Rails 3 API
how to do that. Maybe it's explained somewhere else but not in the
link_to helper docs, as far as I could see.
div class=container
%= render 'layouts/header' %
div class =datos id=datos
%= yield %
/div
%= render 'layouts/footer' %
/div
I am not sure you really want to replace the contents of 'datos'. That
would replace the contents of the whole page except for the header and
the footer.
class PagesController ApplicationController
def about
@title = About
end
end
From the link_to_remote Rails 2.3.8 API:
Returns a link to a remote action defined by options[:url] (using the
url_for format) that’s called in the background using XMLHttpRequest.
The result of that request can then be inserted into a DOM object
whose id can be specified with options[:update]. Usually, the result
would be a partial prepared by the controller with render :partial.
The last sentence is the important one. Your 'about' action does not
render anything, it only assigns a value to a variable. The returned
value of your action will be the string 'About' and that should be
what you get in 'datos' after the code executes, supposing that the
div gets updated.

[Rails] Re: Update div with Prototype
The title variable is to change the title when the page is refreshed.
I believe you are a little lost about how the whole thing works. At
first you said you wanted to change the contents of 'datos' but now
you say you want to change the contents of the tag title. I'll
assume from now on it is the later.
head
title%= title %/title
/head
I think there is a typo in your code. Shouldn't it be %= @title %?.
Besides that, I have never tried to replace the contents of an element
in the header section so I'm not sure it will work. I'd appreciate
if you let me know when you get your code working.
For your code to work you would have to give an id to the element you
want to replace, as in:
title id=title%= @title %/title
Then it might be a good idea to create a partial and render it to
replace the contents of the tag title, although returning just a
string might be OK. You would also need to tell your 'link_to' helper
which HTML element to replace ('title' in this case) and as I
explained before I couldn't see how to do that by looking at the API
with Rails 3. Somebody else already using Rails 3 might be able to
help better than me there.

Then I would try to understand the MVC design pattern, Rails is based on it and will help you tremendously in understanding how things work and why the application looks so 'spread out' in different folders and files. Then I would try to build something really simple like a Hello World type of application, there are many tutorials out there. If you're happy and want to keep going then I would try to learn how to use activerecord, which will be immensely helpful working with any DB.

At that point, you *did* need it. Ugly or repetitive code is an example of a need -- in this case, for refactoring or generalization. There might have been a 'personal' need but I don't think that makes it a *real* need. The ugly code was just the way it is done.

[Rails] Re: select helper with boolean and null/nil values
I believe your problems are coming from the fact that you allow something different than true/false in your DB column. If the column is supposed to contain a boolean value, why are you allowing it to contain the null value? A boolean value is either true or false, not null. If I were you I would force the value to be one or the other and make the column not null capable. You can enforce the rule with one of the validation helpers. This is extracted from the 'validates_presence_of' documentation: If you want to validate the presence of a boolean field (where the real values are true and false), you will want to use validates_inclusion_of :field_name, :in = [true, false]. If you don't want to display errors and just control the issue silently you can always use before_save to change the value to false if needed. Something like: code def before_save self.my_boolean_column = false unless self.my_boolean_column == true end /code You should check against the value true (meaning that you shouldn't leave the equality comparison out) because otherwise you could run into problems if the value is ever something other than true/false/ null. A simple empty string would return true on the condition otherwise as this example shows: # This works in all cases a = true = true puts 'true' if a == true true = nil puts 'true' if a true = nil # This works only when comparing against 'true' a = '' = puts 'true' if a == true = nil puts 'true' if a true # Notice how this would make the code above work incorrectly on the before_save = nil On Nov 18, 3:59 pm, David Cross dcrosst...@gmail.com wrote: I have a boolean column that I would like to modify with a select helper element, and have :include_blank map to (database) null. This *almost* works. On the create/edit/update page, if you select true/yes it sets the column to true, if you select No/false it sets it to false, and if you set it to blank, it sets it to (database) null. fantastic. Now you edit the record. If it is True in the database the select box picks the correct value. If it was set to 'no' or (database)null however the selection is set to the blank value. This is especially problematic if you edit any other field on the form, as it resets *everything* back to 'null', regardless of if it was false or null to beginwith. I have constructed a trivial test application to demonstrate this: http://www.cs.rpi.edu/~crossd/selecttest.tar.bz2 Fire it up in 'rails server' and go tohttp://127.0.0.1:3000/testings (I've included a sqlite3 db there with 2 rows in it). edit one, set it to 'Yes', check the 'show' page, edit it again, set it to 'No', check the 'show' page, edit it again, set it to blank (you won't have to, its already there), and save it and check the show page. notice all 3 edits work correctly, but the initial value is NOT set correctly for for the 'False' case.

[Rails] Re: select helper with boolean and null/nil values
[...]It's perfectly OK to have Boolean columns (or any columns) be null-capable if the semantics of the data dictate that. Sure. However, in my experience most people make boolean columns null capable just because or because it's the default behavior of the DB when defining columns and after a while problems arise because the returned value is expected to be either true or false, not null: It is a boolean column, right? Why doesn't it return true or false? Why do I have to worry about the value being null?. IMHO boolean columns are just a little different because of their very nature. Sure, they can be set to be null but I really don't see the advantage in it. In my experience, if I set the column to default to either true or false (probably false all the time) and change it as needed things work much better and things get easier. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Re: select helper with boolean and null/nil values
IMHO boolean columns are just a little different because of their very nature. I don't see the difference. Where do you see it? Sure, they can be set to be null but I really don't see the advantage in it. I've run across cases where something was best modeled by SQL-style 3-valued logic (for example, yes/no/maybe sorts of things). Why *wouldn't* I use a nullable boolean field for that? Certainly not very 'academic' but from Wikipedia's page http://en.wikipedia.org/wiki/Boolean_data_type: In computer science, the Boolean or logical data type is the most primitive data type, having one of two values (true or false), intended to represent the truth values of logic and Boolean algebra. Why do I think boolean columns are a little different? You could interpret that null is 'similar' to false because it is not true, but that could also be the case the other way around. If you look a the issue from the perspective of well, a boolean column is just a column, yes, I agree, there is no difference. However if you look at boolean columns from the perspective of their most likely reason to exist they are different because they imply that they will always contain a value, either true or false and null is neither. That is different IMO than, for example, a date column, which could very possibly be conceived to contain either a date or no date at all. Could a boolean column be conceived to be null? Certainly, but again, not the most likely case in my experience. Although an interesting proposition I don't think I would ever use a boolean column to store true/false/maybe sort of things. Of course, the column could be created to allow it but that, IMO, would defeat the purpose of the boolean column. I would rather use a different type because, as it happened to me in the past, a 'true/false/maybe' sort of scenario can quickly become a 'true/false/maybe/likely/not that likely/very likely' sort of scenario and then I would need to change my DB and code. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Re: select helper with boolean and null/nil values
Why do I think boolean columns are a little different? You could interpret that null is 'similar' to false because it is not true, But I'm not. I think SQL has it right: null is neither false nor true. Out of context. I never said it was and 'you' meant 'anybody'. Sorry if it was misleading. Don't take things so personally. But that's not even true if we ignore the true 3-valued yes/no/maybe case. The intent of SQL null is to represent *unknown* data. Imagine storing data about your friends, including whether they own a car. You might have a 'has_car' column, which would of course be boolean. Now, you may not know (because you haven't asked) whether some of your friends own a car or not. That is the first thing I ask my friends. Don't you? ;) So what to put in has_car? You can't put true. You can't put false. Guess what, you put null! I'd put I didn't ask but that wouldn't fit in the boolean column... ;) Very true, though. That is different IMO than, for example, a date column, which could very possibly be conceived to contain either a date or no date at all. Could a boolean column be conceived to be null? Yes, absolutely. See above. You have certain ability to repeat yourself. Certainly, but again, not the most likely case in my experience. But common enough. Don't pretend it doesn't happen. Not pretending. Although an interesting proposition I don't think I would ever use a boolean column to store true/false/maybe sort of things. Why not? Fragmented. Because of the explanation I gave. Did you read the whole paragraph? (see below). Of course, the column could be created to allow it but that, IMO, would defeat the purpose of the boolean column. No. SQL booleans are three-valued. It makes sense to use that property. I agree with you in the case of *unkown* data. (From above: you see? this next paragraph explains why. I knew I had written it somewhere!) I would rather use a different type because, as it happened to me in the past, a 'true/false/maybe' sort of scenario can quickly become a 'true/false/maybe/likely/not that likely/very likely' sort of scenario and then I would need to change my DB and code. Then change it *at that time*. Sure, and spend who knows how much time changing DB and code if that happens. You can't know what will happen in the future, and therefore you can't really design for it. Remember YAGNI. Don't overdesign. Don't anticipate if anticipation does not give you a present benefit. YAGNI is a very good principle to follow and I certainly try to adhere to it as much as possible, however it's not the only thing to take into consideration. There is something else I try to use as much as possible, it's called personal experience. There have been times when because of adhering to YAGNI I had to go back and rework A LOT of code. Now I prefer 'overdesigning' a little bit if I see that there is a possibility that not doing so might come back to bite me, even if the only present benefit I get is to have peace of mind and know that I won't get bitten by it. I'd rather spend 30 or 60 extra minutes giving a universal solution to a problem or generating related additional functionality that I might see a use for (but not needed right now) than having to go back and spend days reworking something because of those 'saved' 30 or 60 minutes. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.
