ansible loop over list and dictionary at the same time -


i writing playbook ensure nodes appear in /etc/fstab.

i using loops prevent code duplication.

the logic first check if line appears using grep (with perl regex because multi line) , store results in register.

then want add lines not in fstab file. achieve need loop on list (the register grep return codes) , dictionary (that contains fstab entries).

i having errors parallel loop. tried follow these steps.

one or more undefined variables: 'str object' has no attribute 'item'

tasks/fstab.yaml:

--- - name: make dirs   sudo: yes   file: path={{ item.value }} state=directory   with_dict:     "{{ fstab.paths }}"  - name: check whether declared in fstab   sudo: no   command: grep -pzq '{{ item.value }}' /etc/fstab   register: is_declared   with_dict:     "{{ fstab.regexs }}"  - name: add missing entries   sudo: yes   lineinfile: dest=/etc/fstab line="{{ item.1.item.value }}"   when: item.0.rc == 1   with_together:     - "{{ is_declared.results }}"     - "{{ fstab.entries }}"

vars/main.yml:

--- fstab:   paths:     a: "/mnt/a"     b: "/mnt/b"    regexs:     a: '\n# \(a\)\nfoo1'     b: '\n# \(b\)\nfoo2'    entries:     a: "\n# (a)\nfoo1"     b: "\n# (b)\nfoo2"
  • i not using template on purpose (i want add entries existing files , not on write them).

update: see ansible has module "mount" deals fstab. still looking solution issue because might needed again later on.

i have couple ideas why original approach failing, let's scratch moment. looks you're overcomplicating things- why not use complex list var tie together, , use regexp arg lineinfile module instead of separate regex task? (though sample data should work fine without regexp param) like:

--- - name: make dirs   sudo: yes   file: path={{ item.path }} state=directory   with_items: fstab  - name: add missing entries   sudo: yes   lineinfile: dest=/etc/fstab line={{ item.entry }} regexp={{ item.regex }}   with_items: fstab 
fstab:   - path: /mnt/a     regex: '\n# \(a\)\nfoo1'     entry: "\n# (a)\nfoo1"   - path: /mnt/b     regex: '\n# \(b\)\nfoo2'     entry: '\n# (b)\nfoo2'

i have method allows user access comment have made on site. have post method lets them update comment. my normal solution send entire comment model through, let them update it, update on database when post back. involve sending commentid through in hiddenfor , can manipulated. how can verify commentid sent in get method same i'm getting in post , not able alter comment wish? how can verify commentid sent in method same i'm getting in post? basically have validate following things in post - user logged-in user. authenticated users post comments. commentid in post , should valid commentid , should present in database. userid associated logged-in user should same userid associated comment . comment should contain userid column, can check @ time of update. to make sure update happens comment has been sent in get - hold commentid in session , in post action compare commentid value in session .

javascript - Function overwritting -

is there way overwrite function or event handling in function? using addeventlistener, can have many event handlers on element want var test=document.getelementbyid("div"); test.addeventlistener("click",function(){alert("im first");},false); test.addeventlistener("click",function(){alert("im second");},false); // alerts "im first" , after "im second" but if want overwrite function/event example based on client width example this function one() { alert("first"); } function two() { alert("second"); } window.onresize = function() { var test = document.getelementbyid("div"); if (window.innerwidth > 500) { test.onclick = 1 } else { test.onclick = two; } } is possible in javascript? in case use effective little known approach. addeventlistener can accept object property handleevent event handler. in case it's easy overwr...
