Out of interest though, this passes "author_id" in the params as an empty string, so I have to write: if params.has_key?(:author_id) and not params[:author_id].empty? instead of just: if params.has_key?(:author_id) Does prompt pass any value in in the params?

[Rails] How to create new object with existing nested attributes
Hi,
How would I go about creating a new object with an existing nested
attribute?
class Item < ActiveRecord::Base
has_and_belongs_to_many :attachments
accepts_nested_attributes_for :attachments, :allow_destroy => true
end
i = Item.new
=> #
params = { :attachments_attributes => { "0" => {:id =>
Attachment.find(:last).id.to_s}} }
=> {:attachments_attributes=>{"0"=>{:id=>"62"}}}
i.update_attributes(params)
ActiveRecord::RecordNotFound: Couldn't find Attachment with ID=62 for
Item with ID=
I've tried using Google to find a solution, but to no avail.
Would be very grateful for any advice.

[Rails] Testing file uploads with Carrierwave
Hi, I want to write an application which enables a user to upload a PDF file to our server. I would like to develop this application using a test-driven approach and the Rails default test suite. However, I am not sure what I need to test and what I don't need to test. To elaborate: a user should be able to click on the "select file" button, select a file and press "submit". If the file is a PDF then it will be uploaded to the server and written to the filesystem (as opposed to a database), keeping its original name. If the file is not a PDF, then an error message will be shown and the form will be re-rendered. I would be really grateful if someone could give me some pointers as to what to test here and what not. For example, would it be sensible to test that when a file is selected and the form is submitted, that a file is actually uploaded? Or is this something which would have been tested by the developpers of Carrierwave?

[Rails] Active Record Associations - best way to find all items assosciated with a specific company
I have the following associations in my models:
item.rb
belongs_to :manufacturer, :class_name => "Company"
belongs_to :distributor, :class_name => "Company"
company.rb
has_many :items
My question: what is the best way to find all of the items belonging to
a specific company?
If I call Company.items I (understandably) get the error message:
ActiveRecord::StatementInvalid: SQLite3::SQLException: no such column:
items.company_id: SELECT "items".* FROM "items" WHERE
("items".company_id = ... )
Should I write a little helper method that does what I want, something
along the lines of:
Item.where("items.manufacturer_id LIKE :record OR items.distributor_id
LIKE :record",{:record => @company.id})
or is there a better way to do this through associations?
Would be grateful for any advice.

[Rails] Freezing one gem in Rails 3
Hi, I'm working on an app for a colleague. He has written his own pagination class, but it is buggy and not very DRY. Therefore I replaced it with the well-known "will_paginate" gem, and that works just great. The only problem is, that although this works on my machine, my colleague (for whatever reason) refuses to install any additional gems on his machine (I guess this is why he wrote his own paginator in the first place). My question: is it possible using rails 3.0.3, to unpack ONLY the will_paginate gem to my vendor directory, so that it will work in the project without my colleague having to install it? I tried "bundle install vendor/gems", but this installs everything to this directory.

[Rails] Is it possible to manually wrap a form field in a field_with_errors div after validation?
I am adding an error to a field in a form thus:
company.errors.add_to_base("Please select either distributor or
manufacturer")
However, the add_to_base method doesn't wrap the field where the error
occurred in a field_with_errors div, and thus the field isn't
highlighted.
Is there any way to achieve this manually?
I tried adding a nil error to the attribute:
company.errors.add(:isVertrieb, nil), but this results in the field's
name being output in the list of validation errors.

[Rails] Re: Trouble sending email image attachment with rails
Just an update:
I've checked through the documentation for ActionMailer.
Reusing the example they list in their documentation I now have:
def message(sent_at = Time.now)
from 'b...@example.com'
recipients 'j...@example.com'
subject 'New message'
sent_on sent_at
attachment "image/jpg" do |a|
a.body = File.read("public/images/test.jpg")
a.filename = "hello.jpg"
end
end
test.jpg exists in the folder public/images and is definitely a jpg.
In my previous post I had configured my app to use the mail transfer
agent on my production server (presumably sendmail).
To eliminate this as being the problematic link in the chain I also
configured my rails app to use my gmail account to send the email.
Again the mail generated in my rails app gets delivered, but with the
image attachment I get exactly the same result (jpg doesn't display
inline and when I download it and try to open it I get the message "File
corrupt).
Could anyone give me a clue as to what I am doing wrong?
I'm using rails 2.3.8
Thanks very much in advance.

> Content type is JPEG. File you're reading is PNG.
Yeah, I noticed this too, but according to the book I'm reading this
should work.
I tried sending a jpg as an attachment (instead of a png), but with the
same result. I also tried:
attachment :content_type => "image/png", :body =>
File.read("public/images/rails.png")
but again, in the mail the image displays as broken and when I download
it I cannot open it.
Could I be doing anything else wrong?

[Rails] Trouble sending email image attachment with rails
Hi,
I'm trying to use ActionMailer to send an image as an attachment to an
email. Here's my code:
class ContactMailer < ActionMailer::Base
def message(sent_at = Time.now)
from 'b...@example.com'
recipients 'j...@example.com'
subject 'New message'
sent_on sent_at
body {}
attachment :content_type => "image/jpeg", :body =>
File.read("public/images/rails.png")
end
end
This works, in so far as the email is delivered okay (obviously with
different addresses), but the image attached to the email seems to be
corrupted.
It doesn't display in my mail client and when I download it and try to
open it with a suitable program I get the message that the file is
either too large or corrupted.
I tried replacing the image with a pdf as follows:
attachment :content_type => "application/pdf", :body =>
File.read("public/images/test.pdf")
and this works fine.
Can anybody give me a clue as to what I'm doing wrong?
Thanks in advance.

Hi, I'm confused as to why this code example (from a book) won't work. They want to store a price in cents, but be able to set it and query it in Euros. To this end they are overwriting the getter and setter methods. In my model: class Product < ActiveRecord::Base def price Product.read_attribute(:price)/100.0 end def price=(value) Product.write_attribute(:price, value*100) end end In the console: r = Product.new => # r.price = 10 NoMethodError: undefined method `write_attribute' for # There is no mention of a typo in the book's errata, write_attribute doesn't appear to have been removed from rails, so I'm guessing something changed with rails which makes this not work. I did some googling and saw that shorthand for read/write_attribute() is self[] I tried the following and it worked great: class Product < ActiveRecord::Base def price self[:price]/100.0 end def price=(value) self[:price] = value*100 end end r = Product.new => # r.price = 10 => 10 Could anyone tell me why the first example produces a NoMethodError and the second one works just fine?

Yeah, sorry, I guess I didn't include enough code with my original
question.
I'm (the book is) using the scaffold generator to create both 'employee'
and 'department' resources. The complete update method attempts to
update the attributes of @employee and @employee.department. If this
doesn't work (as validation has failed, for example) it re-renders the
action 'edit'.
def update
@employee = Employee.find(params[:id])
respond_to do |format|
if @employee.update_attributes(params[:employee]) &&
@employee.department.update_attributes(params[:department])
format.html { redirect_to(@employee, :notice => 'Employee was
successfully updated.') }
format.xml { head :ok }
else
@departments = Department.find(:all)
format.html { render :action => "edit" }
format.xml { render :xml => @employee.errors, :status =>
:unprocessable_entity }
end
end
end
Thanks very much for your help.

Here's a snippet of code from the form to edit an existing employee: <% fields_for( @employee.department) do |department_f| %> <%= department_f.label :name,"Department name" %> <%= department_f.text_field :name %> <% end %> The form is submitted to the update action of 'employees_controller.rb', where there is the following code: if @employee.update_attributes(params[:employee]) && @employee.department.update_attributes(params[:department]) ... employee successfully updated ... end My question is about the line "@employee.department.update_attributes(params[:department])" Is it correct to say that this code updates the attributes (in this case "name") of the Department object that is linked (via the "has_many" and "belongs_to" relationship) to the Employee object currently being edited? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Re: Unknown action in Rails App
Cheers for the explanation, Fred.
Following your advice I passed the appropriate HTTP method to the form
in the partial and now everything works as it should.
In case it helps anyone else, I now have:
new.html.erb:
<%= render :partial => "form", :locals => {:url => {:action =>
"create"}, :method => :post} %>
edit.html.erb:
<%= render :partial => "form", :locals => {:url => {:action => "update",
:id => @flight}, :method => :put} %>
_form.html.erb:
<% form_for :flight, :url => url, :html=>{:method=> method} do |f| %>
Thanks again.

[Rails] Unknown action in Rails App
Hi,
I'm following a tutorial which creates a rails project using the
scaffolding generator (in Rails 2.3.8). One of the exercises at the
end of this tutorial is to put the form used in the scaffolding's "new"
and "update" views into a partial.
So, I created a file "_form.html.erb" in the views folder of my app.
In "new.html.erb" I call the partial thus:
<%= render :partial => "form", :locals => {:url => {:action => "create"}
%>
This works as it should and I have no problems creating a new dataset.
In "edit.html.erb" I wrote this:
<%= render :partial => "form", :locals => {:url => {:action => "update",
:id => @flight.id}} %>
but when I try to update an existing record I get the error:
Unknown action
No action responded to 11. Actions: create, destroy, edit, index, new,
show, and update
(where 11 is the id or the object I am trying to update)
Using Firebug to check where the form is being sent, I see:
When I run "rake routes" I see:
PUT /flights/:id(.:format) {:controller=>"flights", :action=>"update"}
What am I missing?
Can anyone point me in the right direction?
Thanks very much in advance.

[Rails] Re: Add line break to custom error message
Just a follow up in case this helps anyone else:
> You could also probably put a literal "" in the error message, then
> use unescape_html.
As it turns out, simple_format was wrapping everything in < p > tags,
which was causing invalid html to be generated in the error view of my
form.
So, I tried Maren's suggestion and came up with the following:
in environment.rb
require 'cgi'
Error message in model:
errors.add(field, "This field is too long.%3cbr %3eYou are using
#{self[field].length} characters out of a permitted #{permitted}.")
And in the view:
<%= CGI.unescape(error_message_on :applicant, :thesis) %>
This works just fine and produces valid markup in the form's error view.
Thanks Maren.

Hi Luke, Thanks very much for the reply.

Hi,
Thanks for the reply.
Sorry, I don't think I expressed myself very well.
When I submit the form, every value the applicant has entered is
validated and passed to the controller. That means that if they enter a
value in the email field (for example) I can access this value in the
controller in the params hash, regardless of whether validation failed
or passed.
As this 'non-represented' field is only getting set after a successful
validation, it is not available in the params hash until everything has
been filled out correctly. Before that it always shows as nil.
I would like to set this value in my model with every form submission
(it is a hash which is always a different value per submission) so that
it is always available in the params has in the controller.
I really appreciate any help.

[Rails] Problem writing to database using form_for
Hi, I have a web-based form for applicants to enter their details, created using form_for :applicant There is one field in the corresponding applicants table of my database which is not represented in the form. I want to set the value of this field in the model (it should be an unique hash). What is the best way to do this? Currently I am doing: validate do |applicant| applicant.check_things applicant.non_represented_field = 123456789 end This works, but the value assigned to the 'non-represented' field is only available after the applicants details have been successfully saved. If validation fails (i.e. if an obligatory field was omitted), this value is showing up in the hash of values that is posted to the controller as nil (which is bad as I always want it to be set). I would be grateful if anyone could give me an idea how to solve this. The only other thing I could think of was setting it with some kind of call back, but I couldn't get that to work.

[Rails] Is it a security risk using eval in the model?
Hi,
If I want to ensure that someone has filled out the email section of a
form I can write this in my model:
validates_presence_of :email
I can also achieve (more or less) the same thing by writing:
validate do |applicant|
applicant.validate_presence("email")
end
def validate_presence(arg)
string = "errors.add(:#{arg}, \"can't be blank\") if #{arg} == \"\""
eval(string)
end
My question: does the method using eval pose any kind of security
threat?
I know the above example is silly (redefining an existing validation
method), but it serves well as a simplified version of what I am trying
to do, without going into unnecessary detail.
Thanks in advance

[Rails] Can save object via console, but not in app's controller
My app has a 'page' model and a 'category' model.
'Page' belongs_to :category.
'Category' has_many :pages.

>> p = Page.new

Yet, when I submit the same data in a post request to my controller,
'category_id' is being ignored.
The page object is created in my controller thus:
@page = Page.new(params[:page])
If I write the contents of 'params[:page]' to WEBrick, I see:
{"title"=>"Test", "body"=>"Test", "category_id"=>"1"}
If I write the contents of @page to the WEBrick, I see:
#
I get the same result on the console:

>> p = Page.new(params)
#
>> p.save
=> false

Am I missing something really obvious?

[Rails] Re: What is @controller instance variable?
Hi, Thanks for all of the replies. That has really made things a lot clearer for me. So, to summarize: 'url_for' is a method defined in ActionController::Base. @controller is an instance variable initiated by ActionController::TestCase containing a reference to my controller (PagesController). PagesController inherits from ApplicationController. ApplicationController inherits from ActionController::Base. Therefore, in ActionController::TestCase, by prepending a method call with @controller, owing to the aforementioned class hierarchy, I can access methods defined in ActionController::Base. Would that be correct? Thanks again for your help. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

To get around this he writes (although this is not the final solution): assert_select "a[href=?]", @controller.url_for(:action => :new, :only_path => true), :text => 'Neue Seite' How is he able to reference a method defined in another class, simply by prefixing the method call with '@controller' Could someone explain what is '@controller' in this context?

[Rails] Re: How to stop a user submitting the same data more than once.
Thanks for the replies. I'm also not sure if doing the validation in the model would work. Assuming that the user has a slow connection and hits submit on the form twice, then the first time the email would be unique, so everything would be good. However, would it not be the case that the second time the user presses submit, the record would have been stored, but the success screen would have not been displayed (hence them feeling the need to press submit a second time). In this case the email address would no longer be unique and an error would be thrown. So, potentially the user could think that their data had not been submitted, when in fact what they would be seeing was an error caused by their second submission (their first having been successful). Nonetheless, thank you very much for the link Aldric. It is definitely useful to understand what is happening behind the scenes in Active Record, and it elaborates on the race conditions Fred mentioned. I will have a play around with validates_uniqueness_of this evening. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Re: How to stop a user submitting the same data more than once.
Thanks for all of the answers. I solved it a little differently and will explain how in case a) it helps anybody else b) there is a flaw in my method which I have overlooked What I did was in the controller: Create a model object: @applicant = Applicant.new(params[:applicant]) Wait for a post request. Look up the last email address sucessfully stored in the database. Check if it is the same as the email address currently being submitted? If so, it is possible that someone has pressed submit twice, or used the back button in their browser. This can therefore be ignored and the user redirected to the success view. If the email adresses are not identical, check if @applicant can be saved. If it can, redirect to success, if it can't re render index view. If the applicant is redirected to the success view without their data being saved (i.e. if both email addresses are the same), then they also receive a flash message that a double data entry was detected for their email address and that the record was only saved once. For this particular application it is not desired that people can apply twice and in practice it rarely happens. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Re: How to stop a user submitting the same data more than once.
I have just finished entering the same data into IE and was rather
surprised to see that I could submit it many times.
So, it seems to be the case that Firefox 3.5 surpresses this behaviour,
whilst IE lets you submit your data as many times as you want.
Do you think it would be possible to stop this by using a session.
In PHP I would do something like this:
session_start();
if (!session_is_registered("counted")){
$query= insert_database();
session_register("counted");
}

[Rails] How to stop a user submitting the same data more than once.
I have a standard form built with rails, which a user to my site can use to submit data. Unfortunately one user just managed to submit exactly the the same data three times in a row. >From the server logs it seems as though he didn't use his back button and then resubmit everything. It looks more like he got a bit fed up waiting for the form to process and pressed the submit button three times. However, I didn't think this was possible in Rails. Is this correct? For the life of me I cannot reproduce this error, even by entering the exact same data the user did and pressing submit ten times in quick succession. Can anyone give me any tips on as to why this might have happened and what I can do to prevent this happening in future.

[Rails] Re: Store data from one form in two separate mysql tables?
I've managed to understand / solve the problem and just wanted to post back here in case it helps anyone else. Having read this: http://bugs.mysql.com/bug.php?id=10035 it appears that this error is caused when a MySQL table has more than 10 columns of the type "text". I tested this by creating a form with 11 text fields. I filled ten of them with input of 15,000 chrs and submitted it - everything fine. I stuck 15,000 characters in the eleventh text field and sure enough the same error was thrown. I started deleting the characters in the eleventh text field and at some point I was able to successfully submit the form. This only appears to be an issue upwards of MySQL 4.1.11 which also explains why my old form (PHP version) didn't crash (it's operating with MySQL 4.0.24) If I understand the advice given on http://bugs.mysql.com/bug.php?id=10035 correctly then the solution to this is to save one's data in two tables, which is what I have done. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Re: Store data from one form in two separate mysql tables?
Thanks for the answer Fred. I am understanding the definition of row size correctly, aren't I? What is happening is that I have a form (with loads of fields - some allowing up to 4000 characters). When a user enters an average amount of data, then the form submits and everything is good. When the user however enters more than an average amount of data and presses submit, the following error message is thrown: ActiveRecord::StatementInvalid (Mysql::Error: Got error 139 from storage engine: ... I did a lot of Googling for "maximum size of a mysql record" and kept finding references to the max. row size (which is, as you say 65535). I took row size to mean the size of one data set (i.e. everything that gets submitted with the form). Is this correct or am I missing something obvious?

end
(where 'user' is the user name and 'pass' is the password).
to my test.

[Rails] 'document.observe' and a variable generated in controller
I have a java script function which I want to call once the page has
loaded.
Initially it looked like this:
I was then advised by people on this forum that it is good practice to
put this into an external js file thus:
document.observe('dom:loaded', function() {
doStuff();
});
That also worked fine.
Now, I want to pass a variable to this function which is generated in my
application's controller (@member)
If I do this in my view, everything works fine:
Yet if I do this in the js file, then nothing works (as might be
expected).
document.observe('dom:loaded', function() {
doStuff(@member);
});
Is there any way to use 'document.observe' in an external js file with a
variable generated in my ruby controller?
If not, what is the best practice in this case?
Thanks in advance

[Rails] Need help 'observe_field' to work in Safari or Konqueror
Hi,
I have a form with two drop down menus.
Depending on what the user selects in the first, the second should be
populated accordingly.
Here is the code I am using to do this.
View (test.html.erb):
<% form_for :applicant, :url=> {:action => "index"} do |f| %>
<%= f.label :topic_1 %>
<%= f.select :topic_1, ["a", "b", "c", "d", "e", "f"], :include_blank =>
true %>
<%= observe_field "applicant_topic_1", :update => "applicant_member_1",
:with => "topic_1", :url => { :controller => "form", :action =>
"get_members_1" } %>
<%= f.label :member_1 %>
<%= f.select :member_1, ["Please select topic 1 first"] %>
---
Controller:
def get_members_1
@members_1 = Member.find_all_by_topic params[:topic_1]
end
---
View (get_members_1.html.erb):
This is no. 1
(I have shortened this for sake of simplicity. Normally a lookup of all
members would take place here)
As you can see, when the user enters something in 'topic_1' the
observe_field helper calls the method 'get_members_1' in the controller,
and updates the field 'member_1' dynamically.
Here is this example in action: http://localhost:3000/test
My problem is that this works fine in FF, IE, Chrome and Opera, but it
doesn't work at all in Konqueror.
I have Googled the problem and come up empty handed.
This is the java script that the helper generates:
Can anybody point me in the right direction to sort this out?
I am relatively ok at ruby / rails, but a beginner regarding java script
/ ajax.
I also had a look on the rails doc page regarding observe_field, but I
cannot see what I am doing wrong.
I would be grateful for any help.

[Rails] How to test that a specific error message is thrown
Hi, If I have this line in my model: validates_presence_of :name, :message => "Please enter a name" and I test this with the following code: def test_should_require_name user= User.new(valid_user_attributes(:name => "")) assert !applicant.save end Is there a way to write an additional test to ensure that not only the name field may not be blank, but that if it is blank the message "Please neter a name" is thrown?

[Rails] Testing fields
Hi,
I have a model named 'applicant'.
Applicant has various fields, one of them is 'date_of_birth'
I have split the field 'date of birth' into three fields:
'dob_day', 'dob_month', 'dob_year'
>From the view:
<% form_for :applicant, :url=> {:action => "index"} do |f| %>
<%= f.label :dob, "Date of birth" %>
<%= f.text_field :dob_day, :maxlength => 2 %>
<%= f.text_field :dob_month, :maxlength => 2 %>
<%= f.text_field :dob_year, :maxlength => 4 %>
<%= error_message_on :applicant, :date_of_birth %>
<% end %>
The idea is that the user then types their date of birth into the text
fields in the form DD-MM-.
As these three fields ('dob_day', 'dob_month', 'dob_year') don't exist
in the database (only 'date_of_birth') does, Rails then looks in the
model, where it finds the following getter and setter methods:
def dob_day=(day)
@dob_day = day
make_date
@dob_day
end
def dob_month=(month)
@dob_month = month
make_date
@dob_month
end
def dob_year=(year)
@dob_year = year
make_date
@dob_year
end
def make_date
if defined? @dob_day and @dob_day != "" and defined? @dob_month and
@dob_month != "" and defined? @dob_year and @dob_year !=""
self.dob = [...@dob_day, @dob_month, @dob_year].join('-')
else
self.dob = ""
end
end
This has the effect that a string in the form of "01-01-2009" is
returned to the field 'date_of_birth'
This works great.
My question: how would I write a test to check that if I set 'dob_day',
'dob_month', 'dob_year' to '01', '01', '2000', that the strig
'01-01-2000' is returned?
I tried this:
def test_should_return_date_of_birth
applicant = Applicant.new(valid_applicant_attributes(:date_of_birth =>
""))
date_of_birth_day = "01"
date_of_birth_month = "01"
date_of_birth_year = "1999"
assert_equal "01-01-1999", applicant.date_of_birth
end
but got the error:
("01-01-1999") expected, but was ("").
And this:
def test_should_return_date_of_birth
applicant = Applicant.new(valid_applicant_attributes(:date_of_birth =>
"", :date_of_birth_day => "01", :date_of_birth_month => "01",
:date_of_birth_year => "1999"))
assert_equal "01-01-09", applicant.date_of_birth
end
but got the error:
unknown attribute: date_of_birth_year
Sorry if this question is long winded, I lack the terminology to explain
it any other way (suggestions welcome).
Thanks for any help you can give.

[Rails] Re: assert_select
Thanks for the answers
I just looked again at the html rails is generating and in fact the
element I'm looking for looks like this:
*
not:
*
Would I test for this like so:
assert_select "form" do
assert_select("span.title.required field", :count => 13)
end
When I run it, I get the error message:
Expected at least 13 elements matching "span.required_field", found 0.
I installed the recommended gem and using that the test works just fine:
assert_xhtml do
form :xpath! => 'count(.//span[ @title= "required field" ]) =
13'
end
One question however, is there any way to turn off the "...in this
sample..." aspect of the output, as if the does find any errors, it
returns my entire html page.
E.g.
1) Failure:
test_index_view(FormControllerTest)
[c:/ruby/lib/ruby/gems/1.8/gems/assert2-0.5.3/lib/assert2/xhtml.rb:327:in
`assert_xhtml'
/test/functional/form_controller_test.rb:41:in `test_index_view'
/test/functional/form_controller_test.rb:37:in `test_index_view']:
Could not find this reference...
...in this sample...

and that does exactly what I want.

Hi, Thanksfor the replies. I've just been chatting with my brother-in-law who is a ruby programmer (considerably better than am I) and he pointed out that as I am calling the method which uses "eval" thus: map_three_fields :dob_day, :dob_month, :dob_year, "make_date", "dob" the method doesn't accept any user input as arguments (only three symbols and two strings) and is therefore harmless. So I guess I can stick with my original method after all.

[Rails] Re: Where to put additional code for model.
Ok, cheers for that. I guess I will have to rethink my approach. In defense of my current method, to make sure the date field doesn't accept incorrect input I use ruby's 'Date.strptime' to parse the string as a date. If it works then everything is ok, if it throws an error then I catch this and output the error message that the date is invalid. >> that make no difference? > You can, of course, do your own sanitizing of input data.

But isn't date_select really feeble?
For example it is very easy to make the whole application crash by
giving date_select false input (eg. enetering 31st February with no
year. http://www.ruby-forum.com/topic/183310)

You're right.
I did have everything working without using eval.
The method with eval was just intended to make everything that bit
neater.
Would it then be sufficient to check the user generated input for
numericality (ie. enduse that the user has only entered numbers as they
are supposed to) and only carry out eval in this case, or would that
make no difference?
