download mechanism

[jdeck88]

The recent commit to the develop branch has some comments on how to complete this task.

We Construct query string to download service like BASE URL: https://www.plantphenology.org/futresapi/v2/download/_search? QUERY SYNTAX: q=+mapped_traits:"humerus+length"++AND+++mapped_traits:"length"' NOTES:

• repeat each query condition as needed, even if they are the same query (e.g. multiple mapped_traits possible).. simply loop $scope.indexVM.filters.jsonObjects and add $scope.indexVM.query.query()... to construct the query string as in the above example
  • include ++AND++ between each term so the query is AND and not OR (which is default)
  • enclose all query values in quotes to prevent searching on individual terms, e.g. "humerus+length" to return instances of 'humerus length' instead of ('humerus' or 'length').
  • replace all spaces with a + for terms inside quotes

Behaviour: After clicking the download BUTTON, need some sort of dialog. This can be either:

1. A dialog with some explanatory text and telling user to wait, with another download button, OR
2. a download progress dialog that closes automatically when complete

Recent commit to develop solved the first part of this issue. Now, we just need the last part, which i've described in code comments, and also here:

// Behaviour: After clicking the download BUTTON, need to download file with call to query service.
// This can be several things, but we need very first, just #1 implemented
//  1. Simply a link to download file and download
//  2. a dialog with some explanatory text and telling user to wait, with another download button, OR
//  3. a download progress dialog that closes automatically when complete
