How to use the 'datepicker' plugin?

Hi Yann-Aël,

I have been playing around with your R package queryBuildR. Thanks for putting the efforts in to build that. Very useful.

I would appreciate a bit of guideance. I am building a Shiny app that intends to apply the quiryBuildR to a dataframe. The data frame contains several columns of a Date (or if easier a POSIXct) class. For those columns, I would like the queryBuildR to show less, less or equal, greater and greater or equal filter options. In that way, I can apply filters relating to date ranges. I had a look at your getFiltersFromTable function and noted that columns of class ‘Date’ or “POSIXct’ are not supported. After some efffort I figuerd out how to adjust the filters to accommodate fro a date class.

Then I was interested to use the 'datepicker' plugin for columns of date or POSIXct class.
I had a look at the JQuery queryBuilder support pages and came up with the following code that should invoke the ‘datepicker’ plugin. However, this appears not to work. I either use the incorrect filter code or the plugin is not (yet) supported in your package.

I now built the following code in my own version of getFiltersFromTable:

MyGetFiltersFromTable <- function(data) {
  filters <- list()
  namesCol <- colnames(data)
  niceNames <- as.vector(sapply(namesCol,idToName))

  for (i in seq_along(namesCol)) {
    filterCol <-
      switch(        
RMA_issue_date = list(
          id = namesCol[i],
          label = niceNames[i],
          type = 'date',
          validation = list(
            format = 'MM/DD/YYYY'
            ),
          plugin = 'datepicker',
          plugin_config = list(
            format ='MM/DD/YYYY',
            todayBtn = 'linked',
            todayHighlight =TRUE,
            autoclose = TRUE
          ),
          operators = list(
            'equal','not_equal','less', 'less_or_equal', 'greater','greater_or_equal','between','in', 'not_in','is_null', 'is_not_null'
          )
        ),
…

I am not sufficiently familiar with javascript jQuery QueryBuilder to determine how to adjust the getFiltersFromTable function or how to install the plugin. Any suggestion are welcomed. Thanks.
