In my Application.cfc, I setup a mapping
this.mappings["/downloads"]="J:\Downloads\documents";
In my template, I have
<cfdirectory action="list" directory="#expandpath("/downloads")#" filter="*.zip|*.docx" name="downloads" recurse="yes">
<!--- <cfdump var="#expandpath("/software")#"> --->
<cfdump var="#downloads#">
<ul>
<cfoutput query="#downloads#">
<li>#downloads.name#</li>
</cfoutput>
</ul>
I'm trying to make the documents downloadable but when the link is clicked, nothing is happening which makes me think my links are not correct however when I mouse over the link, I see the full path which is correct.
What am I missing to make the list of documents clickable?
Here is the URL displayed when mouseover the 3rd document for example.
Since the files are outside of your webroot you will need to have ColdFusion read the file and send it back to the browser.
You will need to create a page, like download.cfm, that can accept a URL parameter to know which file to access. Once you have selected the file you can use something like the following to stream the file.
<cfheader name="Content-disposition" value="attachment;filename=#datafile#">
<cfcontent file="#datafile#" type="application/pdf">
The above code was pulled from https://www.raymondcamden.com/2006/03/10/Ask-a-Jedi-Using-ColdFusion-to-serve-files
WARNING:
Reading URL parameters in this way and giving people access to the filesystem is extremely unsafe. Safer alternatives should be considered before moving something like this into a production environment.
All I needed to do for this exercise is to setup a mapping in my Application.cfc. As others have stated, there is zero security here but for the purpose of this exercise of understanding virtual directories (IIS) and aliases (CommandBox), this is sufficient.
this.mappings["/guides"]="J:\guides";
Then I can use cfdirectory to build my query object
<cfdirectory action="list" directory="j:\guides" recurse="false" name="nameofqry" type="file" sort="datelastmodified desc" filter="*.docx">
Next, perform a cfoutput using my alias as the a href link
<cfoutput query="nameofqry" maxrows="40">
<li>#nameofqry.name#</li>
</cfoutput>
I know coldfusion has some handling for word docs, namely converting them to .pdf. I want to show a document inline without my users having to convert them. Can I programmatically perform the "save as..." int the "wsFormatFilteredHTML" format?
Try this.
If your word content is a variable:
<cfheader name=“Content-disposition” value=“attachment;filename=blah.docx”>
<cfcontent type="application/msword" reset="yes">
#wordconent#
If it's an actual file you should be able to serve directly:
<cfcontent type="application/msword" file="path/filename.docx">
That's from memory so it might take some trial and error. good luck :)
It seems that when I use the <cfsavecontent> tag, the output of that is being served by the server (without the variable being outputted), which, to me, kind of defeats the purpose of <cfsavecontent>.
If this is important: my application uses ColdSpring, ModelGlue and Transfer ORM.
Here's my example code in a function:
<cfsavecontent variable="testvar">
<cfinclude template="test.cfm" />
</cfsavecontent>
<cfreturn testvar>
And the template:
<cfdocument format="PDF" pagetype="A4" orientation="portrait" unit="cm">
<cfoutput>
<!--- PDF content here --->
</cfoutput>
</cfdocument>
The PDF content is being parsed by my browser (Google Chrome), while the view hasn't even been loaded in. How can I best prevent this from happening?
Just to clarify: I am not outputting the #testvar# variable yet in this code, though it seems it loads the template in the browser anyways.
To achieve what you're trying to do, should you not simply be using the name attribute of <cfdocument> to put the PDF data into a variable, instead of trying to <cfsavecontent> it?
Disclosure: I've never used <cfdocument> for anything other than proof-of-concept code and testing, but that's what I'm inferring from the docs.
As I also needed to make multiple PDF documents merge, I ended up doing the following. Many thanks to Adam Cameron for providing the solution to my initial issue.
In the template file, I use the <cfdocument> tag with the name attribute to save the PDF in a variable (thanks to Adam Cameron for this)
Then, I store all the PDF documents in an array in their binary format
In my view, I merge the PDF documents together by using <cfpdf>'s merge action, and using a cfloop, to loop over the array, inside it.
Finally, I display the content by using <cfcontent> and using the variable attribute with toBinary(myPdf)
This got me to where I am.
cfinclude will process the test.cfm page, and the way you configured cfdocument will cause "opening" of pdf document in your browser.
You can prevent openning of this file by saving file on the disc:
<cfdocument format="PDF" pagetype="A4" orientation="portrait" unit="cm" filename ="test.pdf" overwrite ="yes">
But this will not prevent execution of cfinclude in the cfcontent tag, it will just prevent opening in the browser.
You can observe cfinclude as request to the server, it will always be executed.
The solution would be to invoke request on test.cfm file which contains cfdocument in the moment that you actually want to generate pdf.
Example: Use javascript on client to invoke report service which will generate and pop out the screen with pdf report.
Hope this helps.
Using Coldfusion's SpreadSheet() object I have created an excel file and now the user needs to be able to download it.
mySS = SpreadsheetNew();
format1 = StructNew();
format1.color="dark_green";
format1.size="24";
SpreadSheetSetCellValue(mySS, 7,2,3);
SpreadSheetFormatCell(mySS, format1, 2, 3);
essentially I would like something like
<cfdownload var="#mySS#">
however it's almost never that simple. I realize that I can write the file and then use cfheader \ cfcontent however I am trying to avoid writing the file if possible.
Edit
Based on the suggestion I got from speshak I tried
<cfcontent variable="#mySS#" type="application/msexcel">
and the error I got was, am I missing something?
coldfusion.excel.ExcelInfo is not a supported variable type. The
variable is expected to contain binary data.
Alright so thanks to Raymond Camden's Post and speshak here is the final solution.
<cfheader name="Content-Disposition" value="attachment;filename=filename.xls">
<cfcontent variable="#spreadsheetReadBinary(mySS)#" type="application/msexcel">
Try:
<cfcontent variable="#mySS#">
You probably want to set the type attribute as well so the browser knows it's not HTML.
I am trying to store coldfusion code in a database to be used for the subject of a cfmail. The code stored is as follows:
"RE: <cfif myData.general.legalName NEQ """"> {{dotlegalname}}<cfelse>{{docketLegalName}}</cfif>,
DOT## {{dot}}, Docket ##(s) {{docketString}}"
When I retrieve string from the database, I use cfsavecontent to attempt to evaluate it.
<cfsavecontent variable="subject">
<cfoutput>#myData.email.subject#</cfoutput>
</cfsavecontent>
I also tried
<cfsavecontent variable="subject">
<cfoutput>#evaluate(myData.email.subject)#</cfoutput>
</cfsavecontent>
And then I replace all the {{ }} with the appropriate values.
However, the subject of the email is stubbornly refusing to contain an evaluated cfif, and is instead showing the cfif as if it were a string.
Any ideas?
The only way to dynamically evaluate code that you are creating at runtime is via writing it out to a file, and then executing it.
The easiest way would be to write it a .cfm page in the Virtual File System (probably name the file after a UUID, so it's unique), and then it where you need to run the contents.
I wouldn't normally advocate generating code at runtime like this, but it can be the most elegant solution in some cases.
As an alternative, instead of storing the CFML code in the database, you have a set of CFML email template files that get stored in a directory on your server, and in your database you simply record which template needs to be included either via cfinclude or cfmodule.
You can't dynamically evaluate CFML stored in a database without first writing it to file and then using <cfinclude> to include it.
Further to Mark's answer here is some psuedo code:
<cfset fileName = createUUID() & ".cfm">
<cfset fileWrite( fileName, [CODE_FROM_DB]>
<cfinclude template="#fileName#">
<cfset fileDelete( fileName )>
I have used code like this before with no problems. Anything in the Virtual File System flies as it is all run in RAM. For best practice do remember to delete the files created ;)
If you absolutely have to do this, look at the evaluate() function. This, essentially, fires up a new CF thread, compiles the string passed to it, runs it, and returns the result.
If at all possible, I would try to find a way to move your logic to the actual file being run, not the string from the database. I assume you are pulling the data based on some string you've already built, so you might consider appending something to it, so you are looking up subjectDotLegal and subjectDocketLegal or something similar.
Remember, evaluate() is slow, ugly, and can be dangerous (it will run anything passed to it!). If there's a way around it, I suggest you use it.
why not just use something like mustache?
http://mustache.github.com/
https://github.com/pmcelhaney/Mustache.cfc
it has the ability to not only do some of the logic that you want in your script dynamically. i really would suggest you check out the project and maybe even improve and contribute on it.
OH and just for the chance to be on a soapbox: I've been emailing Adobe for years saying that we need the ability to dynamically parse and render CFML. Sadly my cries have only gotten ignored. maybe if more people complained that this feature needs to be added, it would get the attention it deserves.
To give an example: Assume code.txt is a text file that contains the following (just to facilitate simulating CFML stored in a db): <cfoutput>#now()#</cfoutput>
The following code would work:
<cfset q = queryNew("code") />
<cfset queryAddRow(q,1) />
<cfset querySetCell(q, "code", fileRead(expandPath('code.txt')), 1) />
<cfdump var="#q#">
<cfset newCodeFile = expandPath('dynamic.cfm') />
<cfset fileWrite(newCodeFile, q.code[1]) />
<cfinclude template="dynamic.cfm" />
In OpenBlueDragon there is the render function, which can do this.
You can mimic this function in Railo by creating a custom built-in function that saves the file into RAM then cfincludes it, using the following code:
<cffunction name="render" output="Yes" returntype="string"><!---
---><cfargument name="Code" required="Yes" type="string"><!---
---><cfset local.mapping = {'/render_ram_resource':'ram://'}><!---
---><cfapplication action="update" mappings="#local.mapping#"><!---
---><cfset local.fileName = "/render_ram_resource/_render_" &
createUUID() & ".cfm"><!---
---><cffile action="WRITE" file="#fileName#"
output="#arguments.Code#"><!---
---><cfinclude template="#fileName#"><!---
---><cffile action="DELETE" file="#fileName#"><!---
---></cffunction>
(This looks unusual because it needs to allow output, but prevent extra whitespace, hence why all the comments. Unfortunately SO's syntax highlighting seems to be confused by them.)
If you need an ACF-compatible solution, you'll need to use the regular filesystem and a pre-created mapping. (Well, in ACF9 and above you can use the RAM virtual filesystem, but afaik you can't create mappings on the fly like this.)
There's a better way, namely using in memory files. This way you don't have any I/O on the disk and therefore much faster:
For tags that take logical path, define mapping in Administrator. Execute in-memory CFM pages using the cfinclude tag:
Create a mapping for ram:/// so that it can be used in the tags. In this example, /inmemory is the mapping that points to ram:///.
For tags that take absolute path, specify the syntax as provided in the following example:
You can also delete the file from the ram usinf cffile and action delete.
Here's how I stored my header and footers for all pages in a record. This code can go at the top of each page. But I have it in the APPLICATION.cfm and it seems to be working great.
The key here is not use #pound# signs on your expressions. User [square braces]. The code will pick them and evaluate them and return the result back to the template.
It will substitute the number 0 if it can not evaluate an expression as a means of error handling.
<CFSET FooterID=1234> <!-- ID of the record you want to use -->
<CFQUERY NAME="StoredHeader" Datasource="DS1">
Select Body from templates where id=#FooterID#
</CFQUERY>
<CFSET Parse=StoredHeader.Body>
<CFLOOP CONDITION="FindNoCase('[',Parse,1) GT 0">
<CFSET STB=FindNoCase('[',Parse,1)>
<CFSET ENB=FindNoCase(']',Parse,1)>
<CFIF ENB-STB GT 0>
<CFSET BracketExp=Mid(Parse,STB+1,ENB-1-STB)>
<CFTRY>
<CFSET BracketValue=Evaluate(BracketExp)>
<CFSET Parse=ReplaceNoCase(Parse,'['&BracketExp&']',Evaluate(#BracketExp#))>
<cfcatch type="any">
<div>'Using ZERO 0 for missing <cfoutput>#BracketExp#' </cfoutput> </div>
<CFSET Parse=ReplaceNoCase(Parse,'['&BracketExp&']','0')>
</cfcatch>
</CFTRY>
</CFIF>
</CFLOOP>
<CFSET Footer=Parse>
<cfoutput>FOOTER</cfoutput>
I would try the built-in QuoteName function.
