Tutorial: Deployment in PyCharm
This tutorial aims to take you step-by-step through configuring an managing deployment of your code to remote hosts, using PyCharm.
Before you start
Make sure that:
You are working with PyCharm version 5.0 or higher. This tutorial is prepared with PyCharm 2016.1.
You have access right to a remote host you want your code to be deployed on.
Also note that this tutorial is created on Windows 10 and makes use of the default keyboard shortcuts scheme. If you are working on a different platform, or use another keyboard scheme, the keyboard shortcuts will be different.
Preparing an example
You can use the everlasting sample project.
Thus the preliminary steps are done, and we are ready to take off.
Configuring a deployment server
Click on the main toolbar or press Ctrl+Alt+S to open the Settings/Preferences dialog, and choose the Deployment page (you can access the same page by choosing on the main menu).
Click , then in the Add Server dialog box, type your server name (
MyRemoteServer) and select its type (in our case, this is Local or mounted folder):
OK, the new server is added, but it is still void... It only shows the Web server URL
http://localhost, where you will actually browse your uploaded files.
What is specified in the Connection tab?
Select the directory where the project files will be uploaded. In our case, this is the C:\xampp\htdocs local folder. You can either type the path manually, or press Shift+Enter to open the Select Path dialog.)
What is specified in the Mappings tab?
Next, switch to the Mappings tab. By default, the Local path field contains the path to the project root. However, you can select any other directory within your project tree. Let's assume the default value.
In the Deployment path field (which is by default empty), specify the folder on your server, where PyCharm will upload data from the folder specified in the Local path field (in this example, it's py\Solver ). This path is specified relative to the folder ). This path is specified relative to the folder C:\xampp\htdocs.
And, finally, let's accept the default / value for Web path:
OK, apply changes, and the server is ready to use.
Browsing remote hosts
To make sure your server is up and running, select Remote Host tool window appears on the right of the PyCharm window:in the main menu, and the
Next, let's perform some actions, and see what happens.
First, let's upload one of the files to the remote server.
In the Project Tool Window, right-click a file you want to upload. In our case, let it be the file
Solver.py. On the context menu, choose , and see the upload results.
You can also upload contents of each directory within your project. For example, right-click the parent directory of the
src and choose from the context menu. We now have the entire directory uploaded to the server:
Comparing remote and local versions
There is a local and a remote copy of the file
Solver.py, and they are identical. Let's modify the local version.
To do that, place the caret at the method declaration, and press Ctrl+Shift+Alt+T (or choose rename a method:on the main menu). The popup menu shows all refactorings, available in the current context. Let's choose Rename refactoring, and
Perform refactoring and see the method name and its usage changed.
OK, now we've changed the local version. Let's make sure PyCharm knows about these changes. To do that, again go to the Remote Host Tool Window tool window, and right-click
Solver.py. On the context menu, choose . PyCharm opens the differences viewer, where you can accept changes or reject them, using the buttons , , , , :
In the Remote Host Tool Window tool window, right-click the file
Solver.py, and choose Download from here in the context menu. PyCharm shows a warning:
You can also download an entire directory, if it has been previously uploaded to the server. For example, if you click the parent src directory and choose the same command, all nested files will be downloaded from the server.
Make a preliminary step - rollback the changes to the
Solver.py file (Ctrl+Z). You again see the class
Solver.py with the renamed method.
Solver.py, and in the main menu choose :
PyCharm shows differences viewer, where you can accept individual changes or reject them, using the buttons ,, , ,.
Automatic upload to the default server
When you need to have the exact same files on the server as in a PyCharm project, automatic upload can be of help. Automatic upload means that whenever a change occurs in the IDE, it will be deployed to the default deployment server.
Defining a server as default
A deployment server is considered default if its settings apply by default during automatic upload of changed files. To define a deployment server as the default one, follow these steps:
Choose the desired server on the Deployment page (in our case,
MyRemoteServer). You can open this page it two possible ways: either Settings/Preferences | Build, Execution, Deployment | Deployment, or on the main menu.
Enabling automatic upload
As soon as the default server is set, you can make upload to this server automatic. This can be done in the following two ways:
Open the deployment Options (Settings/Preferences | Deployment | Options or on the main menu), and in the Upload changed files automatically to the default server field choose Always, or On explicit save action. The difference between these two choices is explained in the field description.
In the main menu, select Always mode.. Note that automatic upload in this case is performed in the
It is worth noting that the Always mode is not recommended for deploying to production: incomplete code can be uploaded while developing, potentially breaking the production application.
Uploading external changes
By default, PyCharm also uploads the files if they are changed by some external process, such as a VCS branch change, compilation of SASS or LESS, or a File Watcher. To change this behavior and skip external changes, set Upload changed files to the default server to Always and select the Skip external changes checkbox:
Congrats! You've passed this very basic tutorial and performed the following tasks:
Created and configured a server of your own.
Uploaded and downloaded files and folders.
Compared local and remote versions.
Configured the server as default.
Enabled automatic upload of external changes.
