The permissions of the file itself are irrelevant. Here's a reference which explains the permissions model more clearly than I ever could: Any attempt to access a file's data requires read permission.
Justin Ellingwood Introduction Django is a flexible framework for quickly creating Python applications. By default, Django applications are configured to store data into a lightweight SQLite database file.
While this works well under some loads, a more traditional DBMS can improve performance in production. We will install the necessary software, create database credentials for our application, and then start and configure a new Django project to use this backend.
Prerequisites To get started, you will need a clean Ubuntu The non-root user must be configured with sudo privileges. Learn how to set this up by following our initial server setup guide.
When you are ready to continue, read on. Install the Components from the Ubuntu Repositories Our first step will be install all of the pieces that we need from the repositories. We will install pip, the Python package manager, in order to install and manage our Python components.
We will also install the database software and the associated libraries required to interact with them.
After the installation, you can create the database directory structure by typing: Afterwards, you'll be asked a series of questions. Besides the first question which asks you to choose another administrative password, select yes for each question.
With the installation and initial database configuration out of the way, we can move on to create our database and database user.
Skip ahead to the next section. MariaDB If you prefer MariaDB, you can follow the instructions below to install it and perform the necessary initial configuration. Install the packages from the repositories by typing: You can then run through a simple security script by running: Besides the first question, asking you to choose another administrative password, select yes for each question.
We can start by logging into an interactive session with our database software by typing the following the command is the same regardless of which database software you are using: Afterwards, you will be given a prompt. First, we will create a database for our Django project.
Each project should have its own isolated database for security reasons. We will call our database myproject in this guide, but it's always better to select something more descriptive.
We'll set the default type for the database to UTF-8, which is what Django expects: Next, we will create a database user which we will use to connect to and interact with the database.
Set the password to something strong and secure: For better flexibility, we will install Django and all of its dependencies within a Python virtual environment. You can get the virtualenv package that allows you to create these environments by typing: Move into the directory afterwards: Before we install applications within the virtual environment, we need to activate it.
You can do so by typing: It will look something like this myprojectenv user host: Once your virtual environment is active, you can install Django with pip.
We will also install the mysqlclient package that will allow us to use the database we configured:OperationalError: attempt to write a readonly database in ubuntu server.
Ask Question. (OperationalError) attempt to write a readonly database because www-data has no permission on the file (or on the parent folder) First way: Apply permissions to the user www-data. News and feature lists of Linux and BSD distributions.
I am currently running VMWare on Ubuntu LTS (bit) and since I need to re-install Ubuntu anyway, I thought of perhaps upgrading to Ubuntu Changeset  by jow [backfire] merge r Changeset  by jow [package] relayd: map "ipaddr" option .
I have a SQLite database that I am using for a website. The problem is that when I try to INSERT INTO it, I get a PDOException. SQLSTATE[HY]: General error: 8 attempt to write a readonly database I SSH'd into the server and checked permissions, and the database has the permissions-rw-rw-r When I try to open an Sqlite database created in the simulator (using either the Sqlite Database Browser or the Sqlite Expert browser), I get the message: "File is encrypted or not a database".
SQLite - attempt to write a readonly database Hi Experts, I'm using Windows 7, opening an sqlite file in my documents folder with VS and the amalgamation of sqlite . One day our unit tests started failing on Linux. We run them in Docker. So I struggled to understand what was going on. All tests that run on Sqlite failed with bizarre error: I googled a lot trying.

Do I take this to mean that using any tool is impossible on the Gears' database, since they are encrypted?
