Using a SOAP Web Service with a WSDL is one method, for sure, and here is some documentation on that.

A Flex / Flash application can also make standard HTTP calls, sometimes called REST Web Services. In many cases, REST Web Services will return an XML Document, but that is not required. Any data, including simple text data, can be returned from a REST Web Service.

What many people prefer to do is to use an AMF Gateway with RemoteObject. AMF is a binary format so you’ll get much smaller file size transferred back and forth than the alternatives. It also provides for automatic object translation between your server side objects and client side objects. This can be a time saver in development because you don’t have to parse data to turn it into something Flex can use easily.


You will love this selection, and perhaps some of them will inspire your future project.

Calendly

The first site on the list is a project Railsware had a hand in. Calendly is an online scheduling tool. If you need to make an appointment or schedule an event, you can do this in Calendly and get a shareable link for invitees.
It works with your calendar and helps you connect with your best contacts, prospects, and clients. The website can be integrated with different tools you leverage for daily activities like Salesforce, PayPal, Google Analytics, etc.
And this is how it looks in action:

Everseat

Everseat is a healthcare industry site. It deals with scheduling appointments between patients and healthcare specialists including physicians, dentists, vets, and even hair-stylists.

  • :nameThe output that the user sees in the pull-down menu. This is the value between the <option tags.

  • The next used is submit_tag, which outputs an <input button that submits the form.
    Finally, there is the end method that simply translates into </form.

    Go to your browser and visit http://localhost:3000/book/new. This will give you the following screen.

    Enter some data in this form and then click the Create button. Here i have added the following details into the fields −

    Title: Advance Physics Price: 390 Subject: Physics Description: This is test to create new book

    When you click the Create button, it will call the create method, which does not need any view because this method is using either list or new methods to view the results.

    # DELETE /ponies/1 # DELETE /ponies/1.json def destroy @pony = Pony.find(params[:id]) @pony.destroy respond_to do |format| format.html { redirect_to ponies_url } format.json { head :no_content } format.js { render :layout = false } end end

    At finally controller page is as shown image.

    Now run an application, Output called from http://localhost:3000/ponies/new, it will looks like as following image

    Press on create pony button, it will generate the result as follows

    Now click on back button, it will show all pony created information as shown image

    Till now, we are working on scaffold, now click on destroy button, it will call a pop-up as shown below image, the pop-up works based on Ajax.

    If Click on ok button, it will delete the record from pony. Here I have clicked ok button.

    Use the following command to install bundler gem.tp gem install bundler

    Step 4: Install Rails

    Use the following command for installing Rails version 4.2.4.

    tp install rails -v 4.2.4

    Use the following command to make Rails executable available.

    tp rbenv rehash

    Use the following command for checking the rails version.

    tp rails -v

    Output

    tp Rails 4.2.4

    Ruby on Rails framework requires JavaScript Runtime Environment (Node.js) to manage the features of Rails. Next, we will see how we can use Node.js to manage Asset Pipeline which is a Rails feature.

    Step 5: Install JavaScript Runtime

    Let us install Node.js from the Yum repository.

    We will take Node.js from EPEL yum repository.

    This release pipeline has an enabled CD trigger, which executes a deployment every time a new build artifact is available. Optionally, you can disable the trigger so that your deployments require manual execution.

  • At the left, select Tasks.

    Tasks are the activities your deployment process performs. In this example, a task was created to deploy to Azure App Service.

  • At the right, select View releases to display a history of releases.

  • Select the ellipsis (…) next to a release, and then select Open. You can explore several menus, such as a release summary, associated work items, and tests.

  • Select Commits. This view shows code commits that are associated with this deployment.

  • Select Logs.

  • So, it is not for people dreaming about romantic Paris tours. Total Adventure is for those aimed at mountain peaks and tropics.

    Bookbub

    Sometimes, it is not necessary to travel to explore a new place.

    A good book can help you with that. Alternatively, you can travel and enjoy reading together thanks to BookBub, a website for book discoverers. It works with all major ebook retailers. BookBub members are provided with alluring ebook deals recommended by editorial team experts.

    In addition, you’ll find a plethora of free electronic publications to any taste.

    Teespring

    The last example on our sites using Ruby on Rails list is Teespring. First, it is a website where you can buy a T-shirt with an awesome print. Second, it is a turn-key solution for creative people to run their own business.

    A quick example to illustrate:classUser<ApplicationRecordvalidates:name,presence: trueendCopyirbuser=User.newirbuser.save=falseirbuser.save!ActiveRecord::RecordInvalid: Validation failed: Name can’t be blank Copy

    You can learn more about validations in the Active Record Validations guide.

    7 Callbacks

    Active Record callbacks allow you to attach code to certain events in the life-cycle of your models. This enables you to add behavior to your models by transparently executing code when those events occur, like when you create a new record, update it, destroy it, and so on.

    You can learn more about callbacks in the Active Record Callbacks guide.

    8 Migrations

    Rails provides a domain-specific language for managing a database schema called migrations.

    Suppose that the products table was created using an SQL (or one of its extensions) statement like:CREATETABLEproducts(idint(11)NOTNULLauto_increment,namevarchar(255),PRIMARYKEY(id));Copy

    The schema above declares a table with two columns: id and name. Each row of this table represents a certain product with these two parameters.

    Thus, you would be able to write code like the following:

    p=Product.newp.name=”Some Book”putsp.name# “Some Book”Copy

    4 Overriding the Naming Conventions

    What if you need to follow a different naming convention or need to use your Rails application with a legacy database? No problem, you can easily override the default conventions.

    ApplicationRecord inherits from ActiveRecord::Base, which defines a number of helpful methods.

    It will perform better than form_tag. Why because it will create interaction with the Model easily. Therefore it is better to use form_for tag whenever you need interaction between the model and the form fields.

    At this point, we need some modification in the list method’s view file.

    Go to the <li</li element and modify it to look like the following −

    <li <%= link_to c.title, {:action = “show”, :id = c.id} -% <b <%= link_to ‘Edit’, {:action = “edit”, :id = c.id} %</b </li

    Now, try to browse books using the http://localhost:3000/book/list. It will give you the listing of all the books along with Edit option. When you click the Edit option, then you will have next screen as follows −

    Now, you edit this information and then click the Save Changes button.

    Use the following command to create a PostgreSQl database cluster.tp sudo postgresql-setup initdb

    Use the following command to start and enable PostgreSQL.

    tp sudo systemctl start postgresql tp sudo systemctl enable postgresql

    Keeping Rails Up-to-Date

    Assuming you have installed Rails using RubyGems, keeping it up-to-date is relatively easy. We can use the same command in both Windows and Linux platform.

    Use the following command −

    tp gem update rails

    Output

    The following screenshot shows a Windows command prompt. The Linux terminal also provides the same output.

    This will automatically update your Rails installation.

    The next time you restart your application, it will pick up this latest version of Rails.

    There are several methods that you can use to check your models and validate that an attribute value is not empty, is unique and not already in the database, follows a specific format, and many more.

    Validation is a very important issue to consider when persisting to the database, so the methods save and update take it into account when running: they return false when validation fails and they don’t actually perform any operations on the database. All of these have a bang counterpart (that is, save! and update!), which are stricter in that they raise the exception ActiveRecord::RecordInvalid if validation fails.
