Open app/controllers/admin/book_controller.rb and add the lines shown in bold to the new and create actions. def new load_data @book = Book.new end def create @book = Book.new(params[:book]) if @book.save flash[:notice] = 'Book was successfully created.' redirect_to :action => 'list' else load_data render :action => 'new' end end Also, add the following method to the end of the controller: private def load_data @authors = Author.find(:all) @publishers = Publisher.find(:all) end Note that the new method load_data should be declared private, as it is used only internally by the controller. This method loads all authors and publishers from the database and stores them as instance variables, which allows you to access them from the view. We also needed to change the create action, since it will render the new action s view, which expects to find the authors and publishers, if there is a validation error on the Book object. The form shown on the add book page is generated by the app/views/admin/book/ _form.rhtml file. This file is shared by both the edit and add book pages. gtin c# c# - Calculate GS1 / SSCC / UPC check digit - Code Review Stack ...

You can cut/paste these commands into phpMyAdmin or any MySQL client: SET FOREIGN_KEY_CHECKS=0; TRUNCATE `sales_order`; TRUNCATE `sales_order_datetime`; TRUNCATE `sales_order_decimal`; Feel free to experiment with these functions and functions of your own until you are confident that you understand how this stuff works. ean 13 generator c# Calculate checksum for Ean13 barcode number - Experts Exchange

All you need is to drag and drop or add reference and copy sample code. See: How to create barcode in .NET WinForms with Visual C#. You can use this lightweight .NET barcode encoder software library SDK to print and add EAN-13 linear barcodes in Crystal Reports as well. Next, we will use the collection_select view helper to generate the drop-down list for publishers. The format for the collection_select helper is as follows: <%= collection_select :book, :publisher_id, @publishers, :id, :name %> The first and second parameters tell the helper to which model and attribute to bind the field. The third parameter is used to pass a list of publishers that should be shown in the dropdown list. The two last parameters, :id and :name, are used to specify that the value for the drop-down list should be the publisher s id and that the label should be the publisher s name. select_tag is used for generating a list of authors from which George can select one or more authors. The format for this helper is as follows: <%= select_tag 'book[author_ids][]', options_from_collection_for_select(@authors, :id, :name, @book.authors.collect{|author| author.id}), { :multiple => true, :size => 5 } %> select_tag has the following parameters: The first parameter, book[author_ids][], specifies to which attribute the field should be bound. Note that the parameter must end with [] so that Rails knows that the attribute it needs to bind the value to is an array. The second parameter, options_from_collection_for_select, is used for generating the list of options that should be shown in the list. This method s first parameter is a collection of authors. The method s second and third parameters, :id and :name, specify the attributes that should be used as the value and label, respectively. The fourth parameter is used for preselecting the authors that have been assigned to the book. The third parameter of the select_tag is used for specifying options. In this case, we specify that the list should support multiple-selections and that five authors should be shown. c# ean 13 check Creating EAN-13 Barcodes with C# - CodeProject

So, after the assignment x = 1, the name x refers to the value 1. It s almost like using dictionaries, where keys refer to values, except that you re using an invisible dictionary. Actually, this isn t far from the truth. There is a built-in function called vars, which returns this dictionary: >>> >>> >>> 1 >>> >>> 2 x = 1 scope = vars() scope['x'] scope['x'] += 1 x Next, change the app/views/admin/book/_form.rhtml file as follows: <%= error_messages_for 'book' %> <p><label for="book_title">Title</label><br/> <%= text_field 'book', 'title' %></p> <p><label for="book_publisher">Publisher</label><br/> <%= collection_select :book, :publisher_id, @publishers, :id, :name %></p> <p><label for="book[author_ids][]">Authors</label><br/> <%= select_tag 'book[author_ids][]', options_from_collection_for_select(@authors, :id, :name, @book.authors.collect{|author| author.id}), { :multiple => true, :size => 5 } %> </p> <p><label for="book_published_at">Published at</label><br/> <%= datetime_select 'book', 'published_at' %></p> <p><label for="book_isbn">Isbn</label><br/> <%= text_field 'book', 'isbn' %></p> <p><label for="book_blurb">Blurb</label><br/> <%= text_area 'book', 'blurb' %></p> <p><label for="book_price">Price</label><br/> <%= text_field 'book', 'price' %></p> <p><label for="book_price">Page count</label><br/> <%= text_field 'book', 'page_count' %></p> check digit ean 13 c# C# Programming How to Create EAN-13 Barcode Generator ...
