I am trying to use date_select with some of my forms.
<div class="field">
<%= f.label :begin_date %>
<br/>
<%= f.date_select(:begin_date,:start_year => Time.now.year) %>
</div>
Reading through the documentation, I was expecting to get three select tags. What I got was: begin_date(1i), begin_date(2i), begin_date(3i)
If I include these in my model:
attr_accessible :begin_date(1i), :begin_date(2i), :begin_date(3i),
The IDE does not like it. What am I doing wrong? Also, is there a date select method that would return the values in a single tag, instead of 3?
You can just do attr_accessible :begin_date, and it will stitch together the date components into a single Date value for you.

I'm using Ransack to add a search function to my rails app and I'm also using Money-rails gem to handle price and currency.
I want to enter a price in Dollars in the Ransack search field and then it converts it to cents in order to find it in the relevant table.
So basically the problem is how to convert the input form Dollars to cents before submitting the search with Ransack.
Search form:
<div class="form-group">
<%= f.label :price_cents_gteq, "Price between" %>
<%= f.text_field :price_cents_gteq %>
<%= f.label :price_cents_lteq, "And" %>
<%= f.text_field :price_cents_lteq %>
</div>
Thanks a lot in advance!
Custom predicate can solve the problem.
You can use formatter proc to convert dollar to cents. Problems can arise when you will display ransack object value of price.
Update #1
Or even better, you can solve it with ransacker class method.
Update #2
Here is the raw solution with model and ransaker method:
# model
ransacker :price_money, type: :integer, formatter: proc { |dollars| dollars * 100 } do |p|
p.table[:price_cents]
end
# form in view
<%= f.number_field :price_money_gteq %>
<%= f.number_field :price_money_lteq %>
I need to get an array of strings from f.text_field and store it into a database.
<div>
<%= f.label :name %>
<%= f.text_field :name %>
</div>
<div>
<%= f.label :tags %>
<%= f.text_field :tags%>
</div>
tags is an attribute and it is in an array. Name stores into the database correctly but nothing to tags.
How can i do this?
Thanks
You'll probably want to either parse that on the client side with JS to create an array that gets stored in a hidden field, or something similar. Alternatively, you should pass the raw text to the controller and parse it ruby. You should probably do the latter as you will probably want to sanitize the input.
There is a very good gem available for handling tagging. It's called acts-as-taggable and is found here https://github.com/mbleigh/acts-as-taggable-on
I'm brand new to ROR. I'm having a pretty simple problem that I can't find the solution to anywhere. In one of my projects I have a field to enter the date. The problem is that for lots of the data that I gather the date is missing. I don't know how to make that null. My form.html looks like this.
<div class="field">
<%= f.label :date %><br />
<%= f.date_select :date %>
</div>
I imagine that just need to add something to this to allow there to be no date entered. Does anyone know how to allow null entries in a date field?
Thanks
You can use the following option to allow blanks if that's what you mean:
<%= f.date_select :date, :include_blank => true %>
You can then leave it blank, so it becomes NULL in your DB.
I just working on a simple Ruby on Rails application that keeps the data information of staff, but I realized that I needed a way to check that the date of employment will definitely need to be the beginning of the date of resignation.
<div class="field">
<%= f.label :date_of_employment %><br />
<%= f.date_select :date_of_employment, :start_year =>1990 %>
</div>
<div class="field">
<%= f.label :date_of_resignation %><br />
<%= date_select :date_of_resignation, :start_year => Time.now %>
You should check validates timeliness gem, if you are happy to add outside code to your project. It adds all kinds of time/date based validations.
Including validating that one field is before/after another. For instance, the following commands could be used in you model:
validates_datetime :date_of_resignation, :after => :date_of_employment
This gem doesn't rely on javascript to work, it's pure Ruby.
One of the simple solution you can consider is to have a javascript function to verify these two date on form submit. This way your server does not need to process invalid data.
We can perform validation at Rails model level before saving to database. For example these lines of code in the model will validate the data before saving
validate :verify_date
def verify_date
errors.add("Invalid date") if date_of_resignation < date_of_employment
end
I have a birth_date field that is stored as a datetime value. The default rails form helpers spit out a not-too-friendly format, e.g. "2008-06-10 22:33:19.000000". The below is the vanilla rails way.
<div class="field">
<%= f.label :birth_date %>
<%= f.text_field :birth_date, :size=>"20" %>
</div>
How can I simply apply a format? I tried various approaches, for example strftime should work, I thought. But when I try the following, I get an error undefined method 'strftime' for nil:NilClass
<div class="field">
<%= f.label :birth_date %>
<%= f.text_field :birth_date, :value=>f.object.birth_date.strftime('%m/%d/%Y'), :size=>"20" %>
</div>
Based on some other questions/answers, I tried the following. It works for non-null values, but it is ugly code, and it doesn't work for blank values (actually it shows today's date).
<div class="field">
<%= f.label :birth_date %>
<%= f.text_field :birth_date, :value=> Time.parse(f.object.birth_date.to_s).strftime('%m/%d/%Y'), :size=>"20" %>
</div>
In playing around, it seems that outputting f.object.birth_date is treated as a date, rather than datetime. However, when displayed in the text_field (original, ugly formatting), it includes the time. It is friday afternoon, and my combined lack of familiarity with rails forms and ruby date/time objects is making me feel foolish.
Any simple way to get my form to display nothing if null/blank, and a friendly date otherwise?
If you want a blank string if birth_date is empty, you should simply check that birth_date is non-nil beforehand:
<%= f.text_field :birth_date, :value => (f.object.birth_date.strftime('%m/%d/%Y') if f.object.birth_date), :size => "20" %>
This way, when birth_date is nil, :value gets set to nil.
Have you tried using the date_select form builder helper method? You can also use datetime_select, but it looks like you just want to work with the date here.
<div class="field">
<%= f.label :birth_date %>
<%= f.date_select :birth_date %>
</div>
The API docs are here: http://api.rubyonrails.org/classes/ActionView/Helpers/DateHelper.html#method-i-date_select
Add on the options you need.
I've always used that approach, or a javascript date selector like this one from jQuery UI. There are plugins for most JS frameworks these days.
If it MUST be a text_field, use a human language date parsing library like chronic. It'll work, but will require that you parse the input from the form somewhere before applying the attribute to your object.
