![]() ![]() So first of all, let's give this a name here. And you may have noticed under these examples here, there's this memory example. I'm going to create another database connection and just like last time I'll select a SQLite. We can also use this alongside other Ignition features such as named queries or the alarm journal. It works just like any other SQLite Database Connection, in that you can create tables in here, and start writing queries. So now we can use the SQLite Database Connection to start storing things. If we head back to our directory, we can see that the database was created. And we can see it's valid and it's up and running. Let's scroll down and create the connection. Be mindful of storing sensitive information here in these connections. ![]() Looking at the username and password here, we don't use any authentication for SQLite, so I'll leave those blank. So I'm going to add a backslash and then type in the name of the file I want to create. Now we do need to point this URL to a file. As long as the folders along the path exist. So backslashes are used in between folders and files, but the driver would work here with forward slashes as well. I'm using a Windows Operating System, obviously. Just got a backspace so that you can see what I did, and I'm going to paste that path I just copied. I'll head back to the connect URL and I'm going to replace everything after the 'JDBC:SQLite' part here. Now I'm going to select this path and copy. It's empty right now, but I'm going to have the SQLite Database Connection, create the database inside of this folder. Now off-screen here, I have a folder I created inside of my Ignition Installation Directory. Unlike other connection types, we simply need to provide a file path to either an existing SQLite Database file or provide a path to a nonexistent file, which will cause this connection to create the database for us. And let's give this connection a name here, much like other database connection types and ignition. And from my list of options here, I'm going to select the SQLite option. So I'll click on the create new database connection link. And instead, I'm going to create a SQLite Database. I do have a MySQL database connection, but we're going to ignore that. I am under the config section here, under databases and connections. Speaking of getting started, I'm looking at my Gateway. Once you have Ignition installed, you can create a connection and get started. What's nice about SQLite is that you don't need to install any separate software to use it with your Gateway. This differs from Client-Server Database Management Systems like Postgres and MariaDB, which are standalone programs. It's designed to be embedded into other programs. SQLite is a lightweight self-contained SQL Database. Let me know if a stack trace is necessary.In this lesson we'll take a look at creating SQLite database connections. Request URL: Exception Type: OperationalErrorĮxception Location: /usr/lib/pymodules/python2.5/django/db/backends/sqlite3/base.py in execute, line 193 If it's useful, here's the entire output: Request Method: POST ![]() However, instead of it being able to write, I get this cryptic error: So I edited the permissions on the file, so that the Apache process had write permissions. When the application didn't have permission to access the file, it gave me this error: Using my Django app, I'm able to read from the database just fine. ![]()
