[bug] acquire_obj.md and acquire_obj.attribute give different results

[chiahaoliu]

For some unknown reason, acquire_obj.md gives whole contents of dictionary, while acquire_obj.attribute yields partially content or even AttributeError.

For example,

in[]: ScanPlan.md
out[]: {....., sc_parms:{exposure: 1, subs: livetable}, sc_usermd:{this:that} }
in[]:ScanPlan.sc_params
out[]: {exposure:1}
in[]: ScanPlan.sc_usermd
out[]: AttributeError

Same to issue #70

I don't understand this example, do you mean

typing myscanplan.md returns {....., sc_parms:{exposure: 1, subs: livetable}, sc_usermd:{this:that} } typing myscanplan.sc_params returns {exposure:1} typing myscanplan.sc_usermd returns AttributeError?

In that case, you have to make sure that sc_usermd is properly assigned in ScanPlan

try:
    self.sc_usermd = kwargs
except someError:   #not sure which it will throw if **kwargs is absent
    self.sc_usermd = {}

sthg like that? S

@chiahaoliu I am not sure what this one is about. Is it fixed?

[chiahaoliu]

Just revisited it. I think it was not a bug, just I misunderstood it. <object_type>_usermd is never an attributes in our design (and it should not be, I agree). <object_type>_usermd is just a dictionary nested inside <object>.md. Close.
