AttributeError: 'ManufacturerProductDetailsRequest' object has no attribute 'keywords'

[clementspeter]

Dear both,

First of all, thank you very much for this API solution.

I wanted to try out the manufacturer_product_details and used the commands below

search_request = ManufacturerProductDetailsRequest(manufacturer_product=part, record_count=10)
manufacturer_details = digikey.manufacturer_product_details(body=search_request)

"part" is set to a manufacturer reference => ERA-3AED681V

The error in the title is given - what am I doing wrong?

Secondly, I noticed the responses from keyword_search and product_details are not iterable.
What is your recommendation to treat the output result (getting all the returned information into a dictionary)?

Thank you very much for your time,
Best,
Peter

@clementspeter to convert to dictionary you can use the following method:

digikey.product_details(part).to_dict()

With part being the part number.

[clementspeter]

Dear Francois,
Thank you for your answer - I'll try this out.

Have you succeeded in getting the manufacturer_product_details function to work?
Are you able to reproduce the error message?
Looking forward understanding what I did wrong.

[eeintech]

@clementspeter No I haven't tried that function, I'm getting all data I need with the product_details method

[clementspeter]

@eeintech thanks, do all 3 functions (search / product details and manufacturer_product_details) provide the same output? What would be the interest?

I just tried the dict command and it works, thanks for the hint!

[clementspeter]

To phrase it differently: when should which function ideally be used / provides the most accurate or complete results?

[Funkenjaeger]

This was a simple bug. I fixed it in my fork (https://github.com/Funkenjaeger/digikey-api)

Regarding the difference between the three functions, I suggest referring to the DigiKey API definitions, which this library is just faithfully interfacing.
At a glance I believe that the distinctions are, from most specific to most generic:

• product_details() returns product details for a specific digikey part number (can also use a manufacturer part number, but be aware that it only returns one result even if there are multiple matches, so you may get the wrong part)
• manufacturer_product_details() returns search results for a manufacturer part number
• keyword_search() does 'Search by keyword, then narrow down the search using available filters and search options.'

[eeintech]

@Funkenjaeger product_details() also works with manufacturer part numbers 😉

[Funkenjaeger]

@eeintech True, sometimes it does. The actual argument passed to the digikey API is named "digiKeyPartNumber", and the summary in the API description states "Works best with a Digi-Key part number. Some manufacturer part numbers conflict with unrelated parts and may not return the correct product."

I've updated my above comment to reflect that technically, using MPN is possible, but at your own risk.
An example of where that would bite you would be the part 36-2090-ND (MPN is '2090'), which is a hex standoff. product_details() using the MPN returns an Adafruit LCD display, while manufacturer_product_details() returns a list containing both parts.

[eeintech]

Oh that's interesting. For Ki-nTree my colleagues and I have been solely relying on product_details() and never ran into this issue. I might look closer into manufacturer_product_details() after your PR is approved and merged.

[sebo83910]

Hello,

I do have the same king of error with the following part number: DMT3N4R2U224M3DTA0
Here is what I do:

jsom_bom = digikey.product_details(str(manf)).to_dict()
outputfile = './json/product_details_'+str(manf)+'.json'
with open(outputfile, 'w') as outfile:
        json.dump(jsom_bom, outfile)

The error is the following: TypeError: Object of type datetime is not JSON serializable
Note that I added .to_dict() as specified in the post up here..

[eeintech]

@sebo83910 Assuming you did manf = 'DMT3N4R2U224M3DTA0' and import json this code works (I tested it with Python 3.8 and latest release from this repo).
You may have an issue somewhere else in your code.

[sebo83910]

This is strange:

Also there are plenty of discussion about this error on Google, take a look!

indeed, I solved it like this:

        json.dump(jsom_bom.__str__(), outfile)

Thanks for your help.

@clementspeter No problem, it's a real issue unfortunately. Hoping some activity from @peeter123 to take a look at current PR before proposing a fix.
