Django Development in Chester

Building with Django for Chester organisations, where migrations are code you deploy and are treated as an afterthought. They carry your schema history, they run against production, and two developers working on separate branches will produce conflicting ones — which is discovered at deployment rather than at merge.

Why this comes up

The problem

Two branches each added a migration, both merged cleanly, and the deployment fails because they conflict.

What you get

What we deliver

  • Migrations reviewed like any other code, since they run against production data
  • Conflicting migrations detected in the pipeline rather than at deployment
  • Schema changes separated from data changes, which have different failure modes
  • Long-running migrations planned so they do not lock tables during business hours
  • Reversibility considered, with a stated position where it is not achievable
  • Query counts watched, as related-object access generates queries invisibly

Django Development in Chester — common questions

Why do migration conflicts reach deployment?
Because they merge without complaint. Two files each claiming the same predecessor are valid on their own, and the inconsistency only appears when the framework tries to order them — which happens when you deploy rather than when you merge.
How do we catch them earlier?
Check for conflicts in the pipeline. It is a single command that fails the build when the migration graph has diverged, and adding it converts a deployment failure into a merge-time one that whoever created it can resolve immediately.
What about migrations on large tables?
They need planning. An operation that rewrites or locks a large table can hold it long enough to stop the application, so those changes belong in a maintenance window or in a staged approach that avoids the lock entirely.
Should every migration be reversible?
Where it can be, since a failed deployment is easier to recover. Some genuinely cannot — dropping a column loses data — and the important thing is knowing which ones those are before you need to roll one back.
Do you work with businesses across Cheshire?
Yes. We are based in Leicester, United Kingdom and work with clients throughout North West, including Chester and the surrounding Cheshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Chester businesses do you usually work with?
Compliance-heavy systems for financial services firms, and cross-border trading setups for businesses working into Wales. Beyond that we work across Financial Services, Tourism & Heritage, Retail, Professional Services and Agriculture.
Do you cover the areas around Chester?
Yes — we work throughout North West, including Liverpool, Manchester, Wrexham. Chester is an urban area of roughly 120,000+, and we take on work across the wider Cheshire region rather than the city boundary alone.
