I have an ActiveRecord and when i click on save all records are saved except the date.
My contorller
class UsersController < ApplicationController
def create
puts params[:user]
#user1 = User.new(params[:user])
if #user1.save
saveduser = User.where("fbid = ?",params[:user][:fbid])
unless saveduser.first.nil?
session[:user] = saveduser.first
end
puts "user saved "
redirect_to "/users/dashboard"
else
puts "error while saving user"
end
end
The view
<h3>User Details</h3>
<%= form_for(#user) do |f| %>
<table>
--some columns
<tr>
<td><%= f.label :state %></td>
<td> <%= f.text_field :state %></td>
</tr>
<tr>
<td><%= f.label :dob %></td>
<td> <%= f.text_field :dob %></td>
</tr>
<%= f.hidden_field :fbid %>
</table>
<%= f.submit %>
<% end %>
<table>
In console when create method is called in UserController . I can see
{"username"=>"xxxx.xx.94", "firstname"=>"xxxx", "lastname"=>"Raxxstogi", "emaild"=>"xx.xxx#gmail.com", "city"=>"Los Angeles", "country"=>"USA", "state"=>"CA", "dob"=>"08/13/1983", "fbid"=>"xxx"}
My DB table column is
dob | date | YES | | NULL |
Where is it going wrong?
Thanks
You are using a text_field in your form to save into a Date type field in the DB. Try instead to use the date helper methods as described here:
http://guides.rubyonrails.org/form_helpers.html#using-date-and-time-form-helpers
Ruby doesn't understand your date format. You can fix this by explicitly parsing the date with Date::strptime, perhaps in the model as a setter method:
class User < ActiveRecord::Base
def dob=(date)
date = Date.strptime(date, '%m/%d/%Y') if date.is_a?(String)
write_attribute(:dob, date)
end
end
I would, however, second jordanpg's recommendation to use the date helpers in Rails, unless you know that the format will be the same every time.
it could be the problem with your date format. You can either configure active record to accept this format or convert your date param to Date object using strftime or something like it

I try to create simple search engine but I meet some problmes. I have several search_field in my form and if either is empty should returns all objects. Otherwise when it has any content it should be selected by that content. Below is my sample form:
<%= form_for :product, url: products_path, method: :get do |form| %>
<%= form.search_field :brand %>
<%= form.search_field :model %>
<%= form.search_field :price_from %>
<%= form.search_field :price_to %>
<%= form.submit 'Submit' %>
<% end %>
my model method:
def self.search(search)
where(brand: search[:brand]).where(model: search[:model]).where("price >= ?", search[:price_from]).where("price <= ?", search[:price_to])
end
But the above piece of code is wrong because if I leave some field empty it is treated directly as empty string instead of ignore this field and final result is not correct.
Summary this form should work similarly to filter on online store
You'd could do something like this
def self.search(search)
results = all
results = results.where(brand: search[:brand]) if search[:brand]
results = results.where(model: search[:model]) if search[:model]
results = results.where("price >= ?", search[:price_from]) if search[:price_from]
results = results.where("price <= ?", search[:price_to]) if search[:price_to]
return results
end
Good luck.
I use Rails 4.
I use structure
#users = ActiveRecord::Base.connection.execute("SELECT * FROM users")
#users.each do |row| %>
puts user[0] # id--> 1,2,3,4,5,6
end
#users.fields do |field| %>
puts field.name # --> id, login, password.....
end
how to display the data by column name?
for example
#users.first.field['id']
ActiveRecord::Base.connection.execute( will run the sql but not return anything (or return nil, more accurately). To load the records into memory do
#users = User.all
You don't describe what you want very well. If you literally want "1,2,3,4,5,6" you could do
#users.map(&:id).join(",")
if you wanted, for example, to do a table showing all the user data you could do (in your view)
<% cols = User.column_names %>
<table>
<thead>
<tr>
<% cols.each do |col| %>
<th><%= col %></th>
<% end %>
</tr>
</thead>
<tbody>
<% #users.each do |user| %>
<tr>
<% cols.each do |col| %>
<td><%= user.send(col) %></td>
<% end %>
</tr>
<% end %>
</tbody>
</table>
Like i say i don't know if this is what you actually want to do. Your requirements are a very messy and very vague.
EDIT
If you want to load data out of the database without using an AR model then you can do
#users = ActiveRecord::Base.connection.select_all("select * from users")
this will give you an array of hashes like this
[{"id" => "1", "name" => "foo", "bar" => "baz"}, {"id" => "2", "name" => "chunky", "bar" => "bacon"}, .... ]
which you could then access like
user = #users.first #you've got a hash now
aname = user["name"]
def reports
sql = "select username, email, sign_in_count, current_sign_in_at, \
(select count(*) from foo ft where ft.user_id = u.id and ft.state in ('complete', 'active', 'win', 'lose')) as foo_state, \
(select count(*) from bar where creator_id = u.id and m.state not in ('new','cancelled')) as bar_created, \
from users u where sign_in_count > 0 order by foo_state desc;"
#users = ActiveRecord::Base.connection.execute(sql)
end
So, this query is botched a bit for purposes of showing you something, but not bothering you with the details. This query takes a few different tables, queries them, and returns a new table essentially. I'm using postgreSQL, so this returns a PG::Result object. I can call #users.values to get an array of arrays, but I was wondering if there was a more 'rails-y' way do do this?
I'd like to do something like this in the view:
<%= render partial: 'users/shared/user', collection: #users, as: :user %>
but since it's not an actual ActiveRecord object, I can't seem to do that (although it doesn't throw an error if I try, it just doesn't display anything)
Can ARel accomplish a feat like this? Am I asking too much? Thanks!
For anyone else stumbling upon this... this works to get your info, at least:
<table>
<thead>
<tr>
<% #users.fields.each do |f| %>
<th><%= f %></th>
<% end %>
</tr>
</thead>
<tbody>
<% #users.values.each do |v| %>
<tr>
<% v.each do |a| %>
<td><%= a %></td>
<% end %>
</tr>
<% end %>
</tbody>
</table>
I am trying to email a monthly report which is simple the current month's income compared to the last months.
I have all of that working in my report controller (which references another model called Clinical):
# Clinical income by month report
#clinical_income_by_month = Clinical.select(%q{date_format(transactiondate, '%Y') as year, date_format(transactiondate, '%M') as month, sum(LineBalance) as income})
.where(:payments => 0)
.where('linebalance <> ?', 0)
.where('analysiscode <> ?', 213)
.group(:monthyear)
I then have a partial for the table with the data:
<div class="row">
<div class="twelve columns"><h5>This months income so far is <span style="font-size:1.2em"class="<% if #clinical_income_by_month.first.income >= #clinical_income_by_month.first(:offset => 12).income %>green<% else %>red<% end %> radius label"><%= number_to_currency(#clinical_income_by_month.first.income, :unit => "£", :separator => ".", :delimiter => ",") %></span></h5> <%= #clinical_income_by_month.first.month %> <%= #clinical_income_by_month.first(:offset => 12).year %>'s income was <%= number_to_currency(#clinical_income_by_month.first(:offset => 12).income, :unit => "£", :separator => ".", :delimiter => ",") %>.</div>
</div>
<hr />
<table>
<tr>
<th>Year</th>
<th>Month</th>
<th>Income</th>
</tr>
<% #clinical_income_by_month.each do |c| %>
<tr>
<td><%= c.year %></td>
<td><%= c.month %></td>
<td><%= number_to_currency(c.income, :unit => "£", :separator => ".", :delimiter => ",") %></td>
</tr>
<% end %>
</table>
I would like to be able to pull that partial into my email, or if that's not possible, I would like to show the value of the last income.
<%= #clinical_income_by_month.first.income %>
My email code looks like this:
Finance Report
================================================
<%= number_to_currency(#clinical_income_by_month.first.income) %>
The error I am getting is:
1.9.2-p318 :009 > UserMailer.finance_report().deliver
ActionView::Template::Error: undefined method `first' for nil:NilClass
from /Users/dannymcclelland/Projects/premvet/app/views/user_mailer/finance_report.text.erb:3:in `_app_views_user_mailer_finance_report_text_erb___4501411113534248604_70358523362460'
It works when I pull a value from the standard method:
<%= number_to_currency(Clinical.first.UserID) %>
but not when I call it from the #clinical_income_by_month report I created.
Any pointers would be appreciated!
You need to do something like this:
in user_mailer.rb
def finance_report(clinical_income_by_month)
#clinical_income_by_month = clinical_income_by_month
... # all you had here before
end
And in the controller call it this way:
UserMailer.finance_report(#clinical_income_by_month).deliver
Clearly your #clinical_income_by_month is nil. That means the select query is not returning values as you think it should. This is a model problem. Instead of checking the views, you should fire up the "rails console" and see whether the query returns the values you want.
I have quantity and quantity_received in a table. I want to populate quantity_received with quantity value however if I overwrite this value next time I load the form I want to display the saved value.
<%= fields_for "purchase_item[]", purchase_item do |f| %>
<td><%= f.number_field :quantity_received, :min => 1, :value => purchase_item.quantity, :size => 8 %></td>
<% end %>
Does RoR have some built-in function for that?
Seems like the easiest way would be to set it when you store the original quantity field to avoid having to set it in the form.
What's wrong with the way you're doing it now?
