Pull data with photos

Support

Hi everyone,

In odk, data is pulled from a pre-loaded .csv file. Is it possible to pull data with photos?
Thank you.

Best,
Margaret

Hi Margaret,

I'm not sure. What have you tried so far?

Hi Margaret,

To provide a little more detail...

You should be able to put an image name (e.g., image.jpg) in a row in
a CSV, then use pull-data and calculates to store that name inside a
prompt for an image (try the media::image column). Then if you put the
image.jpg file in the media folder of the form, it should work, but
I've never tried it.

I'll be very interested to see what you find out!

Hi Margaret,

If you are looking at a means to organize and analyze the photos, see my

Also, google fusion tables can be a great tool.

Hi Yaw,

We tried (I think) what you suggested above, but ran into a couple problems:

  1. We can't attach an image to the form in Central unless it is referenced literally (rather than through a variable) in the XLS (we get an error saying that no such attachment is referenced in the form).
  2. If we fake it by adding a row for a single image in the Excel, uploading the form and attachment, and then uploading a new version of the form with the hard-coded image name changed to use a variable, we see the following error in place of the actual image (the path appears to be correct):

File: /storage/emulated/0/Android/data/foo.bar.collect.android/files/projects/d714..../forms//filename.jpg is missing

(It looks like adding the new form version with a variable in the media::image column erased the unreferenced attachment in Central, as we have to upload again to go back to the hard-coded workflow.)

If you have any additional thoughts on how we could accomplish this it would be much appreciated.

@TobiasMcNulty This is a pain point for me as well, I have CSVs that reference many images, so also need to force them into Central. Here's what I do:

  • Add a choice list, eg ref_images to your form, then under the image (and perhaps big-image) column put the filename - I use formulas to build the label / image / big-image values from the name.
  • important : Add a select_one to the form at the very start/end that references this choice list, but has relevance set to false. If you don't do this, the choice list won't end up in the XML and the media won't be required for Central upload. This step may become unnecessary in the future.

Obviously, you will need to keep your internal choice list and required media list in sync.

Are you then trying to use these files as dynamic defaults into an image widget? If so, see my showcase on this, currently it can be done in Collect but not Enketo by prepending filename.ext with jr://images/ and placing this string in the calculation column. I also pull a filtered set of fields from a CSV that have an image and big-image value into a select question in order to show these image(s)
