I am using Wicked pdf gem for creating pdf. It is absolutely working fine on my local. But on production it is giving serious issues. The pdf is generated but in spite of generating a single page it generates 14-15 pages with data like this:
")),this.$.write(e),this.$.close()},find:function(e){return new CKEDITOR.dom.nodeList(this.$.querySelectorAll(e))},findOne:function(e){return(e=this.$.querySelector(e))?new CKEDITOR.dom.element(e):null},_getHtml5ShivFrag:function(){var e=this.getCustomData("html5ShivFrag");return e|| (e=this.$.createDocumentFragment(),CKEDITOR.tools.enableHtml5Elements(e,!0),this.setCustomData("html5ShivFrag",e)),e}}),CKEDITOR.dom.nodeList=function(e){this.$=e},CKEDITOR.dom.nodeList.prototype={count:function(){return this.$.length},getItem:function(e){return 0>e||e>=this.$.length?null:(e=this.$[e])?new CKEDITOR.dom.node(e):null}},CKEDITOR.dom.element=function(e,t){"string"==typeof e&&(e=(t?t.$:document).createElement(e)),CKEDITOR.dom.domObject.call(this,e)},CKEDITOR.dom.element.get=function(e){return(e="string"==typeof e? document.getElementById(e)||document.getElementsByName(e)[0]:e)&&(e.$?e:new CKEDITOR.dom.element(e))},CKEDITOR.dom.element.prototype=new CKEDITOR.dom.node,CKEDITOR.dom.element.createF romHtml=function(e,t){var n=new CKEDITOR.dom.element("div",t);return n.setHtml(e),n.getFirst().remove()},CKEDITOR.dom.element.setMarker=function(e,t,n,i){var r=t.getCustomData("list_marker_id")||t.setCustomData("list_marker_id",CKEDITOR.tools.getNextNumber()).getCustomData("list_marker_id"),o=t.getCustomData("list_marker_names")||t.setCustomData("list_marker_names",{}).getCustomData("list_marker_names");return e[r]=t,o[n]=1,t.setCustomData(n,i)},CKEDITOR.dom.element.clearAllMarkers=function(e){for(var t in e)CKEDITOR.dom.element.clearMarkers(e,e[t],1)},CKEDITOR.dom.element.clearMarkers=function(e,t,n){var i,r=t.getCustomData("list_marker_names"),o=t.getCustomData("list_marker_id");for(i in r)t.removeCustomData(i);t.removeCustomData("list_marker_names"),n&&(t.removeCustomData("list_marker_id"),delete e[o])},function(){function e(e,t){return-1<(" "+e+" ").replace(o," ").indexOf(" "+t+" ")}function t(e){var t=!0;return e.$.id||(e.$.id="cke_tmp_"+CKEDITOR.tools.getNextNumber(),t=!1),functi on(){t||e.removeAttribute("id")}}function n(e,t){var n=CKEDITOR.tools.escapeCss(e.$.id);return"#"+n+" "+t.split(/,\\s*/).join(", #"+n+" ")}function i(e){for(var t=0,n=0,i=a[e].length;i>n;n++)t+=parseInt(this.getComputedStyle(a[e][n])||0,10)||0;return t}var r=document.createElement("_").classList,r="undefined"!=typeof r&&null!==String(r.add).match(/[Native code]/gi),o=/[\\n\\t\\r]/g;CKEDITOR.tools.extend(CKEDITOR.dom.element.prototype, {type:CKEDITOR.NODE_ELEMENT,addClass:r?function(e){return this.$.classList.add(e),this}:function(t){var n=this.$.className;return n&&(e(n,t)||(n+=" "+t)),this.$.className=n||t,this},removeClass:r?function(e){var t=this.$;retur
The entire 14-15 pages are like this.
This is the method that creates pdf.
def generate_supplier_commission_pdf
@start_date = params[:start_date].to_date.strftime('%d/%m/%Y')
@end_date = params[:end_date].to_date.strftime('%d/%m/%Y')
if params[:sec_filter].present?
sec_filter = true
else
sec_filter = false
end
results = get_report_results_by_type(params[:report_type], @start_date, @end_date, sec_filter)
@results = JSON.parse(results)
@type = params[:report_type].to_i
respond_to do |format|
format.html
format.pdf do
render pdf: "report",
layout: 'pdf_layout',
template: 'reports/generate_supplier_commission_pdf.html.erb',
encoding: 'UTF8',
print_media_type: true,
disposition: 'attachment',
page_size: 'letter',
orientation: 'landscape',
lowquality: 'false',
debug: true
end
end
end
Each and everything like the wkhtml path or anything that can be taken of care of in the code is fine. The only difference I saw is in the logs ie after this line
***************WICKED***************
Rendered reports/generate_supplier_commission_pdf.html.erb within layouts/pdf_layout (5.2ms)
The following line is not present on server logs.
"***************[\"/usr/bin/wkhtmltopdf\", \"-q\", \"--orientation\", \"landscape\", \"--page-size\", \"letter\", \"--encoding\", \"UTF8\", \"--lowquality\", \"--print-media-type\", \"file:///tmp/wicked_pdf20160903-24256-1v1ay70.html\", \"/tmp/wicked_pdf_generated_file20160903-24256-1da8k68.pdf\"]***************"
I will be really grateful if someone could point out what is going wrong in this case. Thanks in advance.
I managed to resolve this issue by commenting this line in my config/environments/production.rb
# config.assets.js_compressor = :uglifier
and adding this line in it's place:
config.assets.compress = true
