Как подключить postgresql к pycharm

PostgreSQL

This functionality relies on the Database Tools and SQL plugin, which is bundled and enabled in PyCharm by default. If the relevant features aren’t available, make sure that you didn’t disable the plugin.

The Database Tools and SQL plugin is available only in PyCharm Professional.

1. Press Control+Alt+S to open the IDE settings and then select Plugins .
2. Open the Installed tab, find the Database Tools and SQL plugin, and select the checkbox next to the plugin name.

Official documentation and software

• For full information about PostgreSQL, refer to the official documentation.
• To download PostgreSQL database software, refer to the official software downloads.

This topic presents a general procedure on how you can create a data source for the connection to your PostgreSQL database in PyCharm, and run a test connection. It is assumed that you already have the necessary prerequisites and the database is up and running. For example, if you want to run a database on your machine and connect to that database, the corresponding DBMS software must be installed on the machine first.

Connect to a PostgreSQL database

1. To connect to the database, create a data source that will store your connection details. You can do this using one of the following ways:
   • In the main menu, go to File | New | Data Source and select PostgreSQL .
   • In the Database tool window ( View | Tool Windows | Database ) , click the New icon () in the toolbar. Navigate to Data Source and select PostgreSQL .
2. In the General tab of Data Sources and Drivers dialog right pane, specify the driver and connection type.
   1. In the Driver list, leave the default driver option, unless another driver is required for your connection.
   2. From the Connection type list, select the connection type depending on the connection details that you have:
      • default : connect by using Host , Port , Database , and URL .
      • URL only : connect by using only the URL .

   For the URL only connection type, the JDBC URL that you enter is used as is.

   For the other connection types, the JDBC URL is broken down into connection details. You can either specify them separately and use the automatically generated URL, or you can enter the URL directly in the corresponding field.

Check if there is a Download missing driver files link at the bottom of the connection settings area. Click this link to download drivers that are required to interact with a database. For a direct download link, refer to the JetBrains JDBC drivers page. Location for the downloaded JDBC drivers is the PyCharm configuration directory. You can also use your drivers for the database instead of the provided ones. For more information about connecting to a database with your driver, refer to Add a user driver to an existing connection. If there is no Download missing driver files link, then you already have the required drivers.

Specify the database connection details. Alternatively, paste the JDBC URL in the URL field.

1. In the Host field, type your server address.
2. In the Port field, type the port of PostgreSQL. The default port is 5432. Real port numbers might be different on your system. Verify that you use a correct port number with your database administrator, server settings, or hosting provider.
3. From the Authentication list, select the authentication method that you want to use to authenticate the connection. The following options are available:
   • pgpass : by using the pgpass file. You can store this file in the user’s home directory. You can read more about the password file and its location in The Password File at postgresql.org.
   • User & Password : by using your login and password.
   • No auth : authentication is not required.
4. In the User and Password fields, type your user credentials. To use no password, leave the Password field empty. To delete a once entered password, right-click the Password field and select Set Empty .
5. In the Database field, type the database name to which you want to connect.
6. In the URL field, PyCharm generates the JDBC URL automatically using the values of other connection settings. If you need to use a JDBC URL with certain additional settings, paste it in the URL field. The general URL to use is as follows:
   • Format: jdbc:postgresql://:/
   • Example: jdbc:postgresql://127.0.0.1:5432/myDatabase

For more information about the URL format, refer to the PostgreSQL official documentation.

1. From the Authentication list, select the authentication method that you want to use to authenticate the connection. The following options are available:
   • User & Password : by using your login and password.
   • No auth : authentication is not required.
2. In the User and Password fields, type your user credentials. To use no password, leave the Password field empty. To delete a once entered password, right-click the Password field and select Set Empty .
3. In the URL field, PyCharm generates the JDBC URL automatically using the values of other connection settings. If you need to use a JDBC URL with certain additional settings, paste it in the URL field. For more information about the URL format, refer to the PostgreSQL official documentation.

For the reference information about connection settings and properties on the General and other tabs of Data Sources and Drivers dialog ( Shift+Enter ), see Connection settings and DBMS-specific properties.

Ensure that the connection to the database can be established using the provided details. To do that, click the Test Connection link at the bottom of the connection details area. In case of any connection issues, refer to the Cannot connect to a database page.

(Optional) By default, only the default database and schema are introspected and available to work with. If you also want to work with other databases and schemas, in the Schemas tab, select them for the introspection.

Click OK to create the data source.

Find your new data source in the Database tool window ( Shortcut is missing ) .

• For more information about the Database tool window, see the corresponding reference topic. To see more databases and schemas under your new data source node, click the N of M button and select the ones you need. PyCharm will introspect and show them.
• For more information about working with database objects in PyCharm, refer to Database objects.
• To write and run queries, open the default query console by clicking the data source and pressing F4 .
• To view and edit data of a database object, open Data editor and viewer by double-clicking the object.

Use ⇧⇧ (macOS) / Shift+Shift (Windows/Linux), to bring up the Search Everywhere dialog. You can now search for Database to open the Database tool window which helps you to connect to multiple databases and DDL data sources.

You click on the + (New) button. Select Data Source then Postgres as the data source type. Customize the name of the data source, connection details, then click on the Test link to ensure everything is ok.

Once everything is done, a Console tab will appear and you can now query the database from the IDE. You can also explore it from the Database tool window, and select which parts to hide or show from it.

Note: You may need to download a database driver for the IDE first. If you see a Download driver link, you’ll need to click on that before you can connect to the database.

Alternately, you can open Database tool window from the Sidebar of the IDE:

Удаленный доступ с помощью pgAdmin к базе данных Odoo postgre в Ubuntu¶

** Это для интеграции с PgAdmin, но такой же метод работает с PyCharm. **

ШАГ № 1 — получить pgAdmin Установить pgAdmin с pgadmin.org

ШАГ # 2 — разрешить удаленное подключение к серверу postgre отовсюду Откройте файл etc / postgresql / 9.x / main / pg_hba.conf и добавьте следующую строку: host all all all md5

ШАГ # 3 — пусть сервер postgre слушает всех. Откройте etc / postgresql / 9.x / main / postgresql.conf и измените следующую строку: listen_addresses = ‘*’

ШАГ # 4 — дать пользователю «postgres» пароль. Запустите терминал psql: sudo -u postgres psql. Введите пароль: ALTER USER postgres PASSWORD ‘yourpassword’; Оставьте терминал psql: q

ШАГ # 5 Перезапустите сервер postgre, выполнив команду терминала: sudo /etc/init.d/postgresql restart

ШАГ # 6 Запустите pgAdmin и добавьте соединение с сервером следующим образом:

Как в PyCharm перенести базу данных PostgreSQL

Admin 05.10.2020 , обновлено: 08.01.2021 PostgreSQL

Будем переносить локальную базу данных PostgreSQL на удаленные сервер с помощью программы PyCharm.

Чтобы избежать проблем с пользователями при работе с базами данных на разных системах надо придерживаться одинаковых имен, иначе при импорте возникнут ошибки:

Command was: ALTER TABLE public.users_settings_id_seq OWNER TO «UserName»;
pg_restore: from TOC entry 219; 1259 57835 TABLE volumes UserName
pg_restore: error: could not execute query: ERROR: role «UserName» does not exist

В локальной базе данных ставим курсор на public:

И выбираем Export with ‘pg_dump’:

Выбираем параметры как на скрине ниже и экспортируем в удобную нам папку:

Теперь для удаленного сервера также ставим курсор на директорию public, но теперь выбираем пункт Restore with ‘pg_restore’:

Этот процесс не самый быстрый. Возможно, в следующий раз разберем импортирование другим способом.
