Ecto migration for renaming table with indexes and constraints
Renaming table in Ecto migration
I recently wanted to rename a model and its postgres table in a Phoenix app. Renaming the table was simple and documented, but the table also had constraints, sequences, and indexes that needed to be updated in order for the Ecto model to be able to rely on default naming conventions. I couldn't find any examples of what this would look like but was eventually able to figure it out. For anyone else in the same situation, hopefully this example helps.
In the example below, I'm renaming the Permission model to Membership. This model belongs to a User and an Account, so it has foreign key constraints that need to be renamed.
Install conda and use it to install nextflow and singularity
This guide will show you how to install conda and then use it to install nextflow and singularity for executing popular bioinformatics workflows. Unfortunately, singularity is not available on Windows or macOS. So, this guide will only target Linux environments. If you have to use Windows 10, then try WSL2. If you have to use macOS, then try a Virtual Machine.
