* | Make visitors threadsafe by removing @last_column | Ernie Miller | 2013-04-28 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | | | | The last_column feature of the ToSql visitor and its descendants is what enabled quoting based on the column last visited -- in other words, if you have a standard condition like an equality with a string attribute on the left side and an integer on the right side, then when ARel visits the node, it'll first visit the left side attribute, setting the column of the string attribute as the last column, and resulting in the right side of the condition getting the appropriate quoting. The downside is that this means that visitors can't be shared between threads, because of the state mutation. It also makes for some really weird behavior in the event that the visitor visits a node that happens to contain an attribute you weren't expecting to be there, since it'll potentially quote something based on that attribute. So, it prevents reversing an equality condition. column = value will work, but not value = column, since the last column wouldn't be the column you're hoping for. This is a first pass at fixing this by changing the signature of the visit methods to accept the currently-relevant attribute, if any. | ||||

* | Add equality to ALL THE THINGS (that matter) | Ernie Miller | 2012-08-18 | 28 | -2/+550 |
| | | | | | | | | | | | | People are often trying to use ARel nodes inside ActiveRecord, and when they do so, lots of things can break, because ActiveRecord relies on Array#uniq and sometimes hash key equality to handle values that end up in wheres, havings, etc. By implementing equality for all the nodes, we should hopefully be able to prevent any nodes (even nodes containing other nodes) from failing an equality check they should otherwise pass, and alleviate many of these errors. Fixes #130 | ||||
* | Add Nodes::TableAlias#engine | Jon Leighton | 2012-07-13 | 1 | -0/+16 |
