Serialize keys as strings when using JSON.
Reset attributes when calling
v3.1.0 ChangesDecember 03, 2016
- 👉 Use Nest instead of Nido
A new release of Nest (3.0.0) simplified the interaction with Redis.
- 👉 Use Model#hash for equality
This change just removes some slight redundancy in the code. The external behavior remains unchanged.
v3.0.3 ChangesJune 15, 2016
- 🛠 Fix bug that gave false positives for unique indices.
Uniques were indexed for nil values as empty strings. This release fixes that issue.
v3.0.2 ChangesApril 22, 2016
- 🛠 Fix bug created the wrong keys when indexing floats.
As reported by @slowernet, if an indexed attribute was assigned a real value with 0 fractional part (eg. 3.0), the
tostringfunction in lua truncated the value to an integer. As a result, the index was created with the wrong key (Model:indices:attribute:3, instead of Model:indices:attribute:3.0). The fix is to convert all values to strings before sending them to the Lua script.
v3.0.1 ChangesApril 14, 2016
- Adapt Lua scripts to Redis unstable.
v3.0.0 ChangesApril 13, 2016
- 👉 Use JSON instead of msgpack for internal encoding.
When Ohm started using Lua internally for saving, updating and deleting objects, it used msgpack for serializing. Redis supports both msgpack and JSON, and we picked msgpack because it produces a more compact representation. At some point, the Ruby msgpack library and the internal msgpack support in Redis diverged, and we were forced to lock the dependency to a specific gem version. Recently, some people complained about encoding issues originating from msgpack inside Redis, and once they tried a modified Ohm that uses JSON instead of msgpack, all their issues disappeared. That's why we think it's time for removing msgpack altogether and use JSON instead.
- 🚚 Move the raise of MissingID to Ohm::Model#key.
In previous versions, trying to access an instance's
idwould raise a
MissingIDerror. The reason why raising that error is convenient is because it allows Ohm to fail as early as possible when you try to use an object that hasn't been saved yet. The error can arise from comparisons, from direct calls to
id, and also from any call to methods that need
object.keyto return a proper value, as
keyin turn calls the
idmethod. But it turns out that many form builders rely on the fact that sending the
idmessage to most ORMs results in either a valid ID or
nil, and here Ohm was the exception. By moving the check from
key, we can keep most of the previous behavior and we can return
nilwhen sending the
idmessage to a new instance, thus making Ohm compatible with most form builders.
