Download file android app with yii framwork

This is also commonly needed in practical applications. Instead of taking the trouble to write the actual code, we will use Gii -- a powerful Web-based code generator.

Info: Gii has been available since version 1. Before that, we could use the aforementioned yiic tool to accomplish the same goal. We will be prompted for a password, which should be the one that we just entered in the above application configuration. After login, click on the link Model Generator. This will bring us to the following model generation page,. In the Model Class field, enter User.

Then press the Preview button. This will show us the new code file to be generated. Now press the Generate button. A new file named User. After creating the model class file, we will generate the code that implements the CRUD operations about the user data. We choose the Crud Generator in Gii, shown as follows,. In the Controller ID field, enter user in lower case.

Now press the Preview button followed by the Generate button. We are done with the CRUD code generation. Click the Create User button on the page. We will be brought to the login page if we have not logged in before. After logging in, we see an input form that allows us to add a new user entry. Complete the form and click the Create button.

If there is any input error, a nice error prompt will show up which prevents us from saving the input. Back on the user list page, we should see the newly added user appearing in the list. Repeat the above steps to add more users. Notice that the user list page will automatically paginate the user entries if there are too many to be displayed in one page. This will show us the user entries in a nice tabular format.

We can click on the table header cells to sort the corresponding columns. We can click on the buttons on each row of data to view, update or delete the corresponding row of data. We can browse different pages. We can also filter and search to look for the data we are interested in. Found a typo or you think this page needs improvement? How is this achieved inside the Yii framework?

If you do not already have Composer installed, you may do so by following the instructions at getcomposer. On Windows, you'll download and run Composer-Setup.

Please refer to the Troubleshooting section of the Composer Documentation if you encounter any problems. If you are new to Composer, we also recommend to read at least the Basic usage section of the Composer documentation. In this guide all composer commands assume you have installed composer globally so that it is available as the composer command. If you are using the composer.

If you had Composer already installed before, make sure you use an up to date version. You can update Composer by running composer self-update. The number of requests depends on the number of dependencies your application has and may be bigger than the Github API rate limit. On fast connections you may hit this limit earlier than Composer can handle so we recommend to configure the access token before installing Yii.

Please refer to the Composer documentation about Github API tokens for instructions on how to do this. With Composer installed, you can install Yii application template by running the following command under a Web-accessible folder:. This will install the latest stable version of Yii application template in a directory named basic. You can choose a different directory name if you want. Info: If the composer create-project command fails you may also refer to the Troubleshooting section of the Composer Documentation for common errors.

When you have fixed the error, you can resume the aborted installation by running composer update inside of the basic directory. Tip: If you want to install the latest development version of Yii, you may use the following command instead, which adds a stability option :.

Note that the development version of Yii should not be used for production as it may break your running code. The above installation instructions show how to install Yii, which also creates a basic Web application that works out of the box. This approach is a good starting point for most projects, either small or big. It is especially suitable if you just start learning Yii. This can be achieved either by usage of asset-packagist.
